Direct conversion of carboxylic acids to ureas, carbamates, and thiocarbamates in a single pot via Curtius rearrangement is accomplished. One recently established coupling reagent, Ethyl-2-cyano-2-(2-nitrophenylsulfonyloximino)acetate (ortho-NosylOXY, I), is successfully used for the racemization free synthesis of ureas, di-peptidyl ureas, and carbamates with moderate to good yield (82-69%). This single-pot hassle-free procedure works with a diverse range of N-protecting groups Fmoc, Boc, and Cbz. Various amine, including aromatic, methyl esters of amino acids, t-butylamine, alcohols, and thiols, are used as nucleophiles. A detailed NMR-based mechanism study is incorporated here. Racemization suppression, easy removal of by-products, and less waste generation make this methodology useful.

Arylation of carbonyls, one of the most common approaches toward alcohols, has received tremendous attention, as alcohols are important feedstocks and building blocks in organic synthesis. Despite great progress, there is still a great gap to develop an ideal arylation method featuring mild conditions, good functional group tolerance, and readily available starting materials. We now show that electrochemical arylation can fill the gap. By taking advantage of synthetic electrochemistry, commercially available aldehydes (ketones) and benzylic alcohols can be readily arylated to provide a general and scalable access to structurally diverse alcohols (97 examples, >10 gram-scale). More importantly, convergent paired electrolysis, the ideal but challenging electrochemical technology, was employed to transform low-value alcohols into more useful alcohols. Detailed mechanism study suggests that two plausible pathways are involved in the redox neutral alpha-arylation of benzylic alcohols.

A general and efficient method for the deconjugative alpha-alkylation of alpha,beta-unsaturated aldehydes promoted by a synergistic effect between (BuOK)-Bu-t and NaH, which considerably increases the reaction rate under mild conditions, is reported. The beta,gamma-unsaturated aldehyde, resulting from the alpha-alkylation, is transformed in high yield into the corresponding allyl acetate via a lead(IV) acetate-mediated oxidative fragmentation. This strategy could be used for the construction of the carbon skeleton of a wide variety of alkyl or arylterpenoids.

The neutral trichloro[hydrotris(1-pyrazolyl)methane]vanadium(III) [VCl3(Tpm)] (Tpm = HC(pz)(3); pz = pyrazolyl) C-scorpionate complex was immobilized on amine-functionalized mesoporous silica (aptesSBA-15) via an impregnation method forming the [VCl3(Tpm)]@aptesSBA-15 composite. The immobilization of the vanadium compound was confirmed by several characterization techniques, namely SEM/EDS, powder XRD, FT-IR/ATR, ICP and BET surface area analysis, revealing the successful incorporation of the complex, and confirming the structural and morphological preservation of the porous support and the vanadium complex. The vanadium composite was tested as heterogeneous catalyst for the peroxidative oxidation of benzyl alcohol under mild conditions and its catalytic performance was compared to that of the analogous homogeneous [VCl3(Tpm)] complex. The catalytic studies were extended to other substrates. The effect of various parameters, such as amount and type of oxidant, catalyst and additives, temperature and reaction time were investigated allowing to reach overall yields of ca. 60% and turnover numbers (TONs) up to ca. 7.6 x 10(3). The results obtained demonstrated the higher performance of the heterogeneous catalyst using much less [VCl3(Tpm)] complex under a solvent-free system. Furthermore, consecutive reaction cycles could be performed, showing its recycling capacity. Structural stability was also investigated, indicating the viability of the vanadium C-scorpionate composite as catalyst for other oxidative reactions with high industrial interest.

We report here novel Cu(I) thiophene carbaldimine catalysts for the selective aerobic oxidation of primary alcohols to their corresponding aldehydes and various diols to lactones or lactols. In the presence of the in situ generated Cu(I) species, a persistent radical (2,2,6,6-tetramethylpiperdine-N-oxyl (TEMPO)) and N-methylimidazole (NMI) as an auxiliary ligand, the reaction proceeds under aerobic conditions and at ambient temperature. Especially the catalytic system of 1-(thiophen-2-yl)-N-(4-(trifluoromethoxy)phenyl)methanimine (ligand L2) with copper(I)-iodide showed high reactivity for all kind of alcohols (benzylic, allylic and aliphatic). In the case of benzyl alcohol even 2.5 mol% of copper loading gave quantitative yield. Beside high activity under aerobic conditions, the catalysts ability to oxidize 1,5-pentadiol to the corresponding lactol (86% in 4 h) and Nphenyldiethanolamine to the corresponding morpholine derivate lactol (86% in 24 h) is particularly noteworthy.

Objectives: Inconsistent findings have been reported on the link between dietary carbohydrates and lung cancer. This study aims to comprehensively evaluate the role of dietary carbohydrates on lung cancer risk. Materials and methods: The prospective study is based on the PLCO trial, which recruited 113,096 eligible participants across the United States. Participants had to have completed baseline and diet history questionnaires. The incidence of lung cancer was acquired through self-report and medical record follow-up. A multivariable logistic model adjusted for confounders was used to estimate odds ratios (ORs) and 95 % confidence intervals (CIs) of dietary carbohydrates, fiber, whole grains, glycemic index (GI) and glycemic load (GL) for lung cancer. Similar methods were applied in analyzing the carbohydrates and fiber from different food sources. Multinomial logistic models were used for sensitivity analysis with lung cancer subtypes as outcomes. Results: Dietary carbohydrates and GL were inversely associated with lung cancer incidence in the PLCO population. Among various carbohydrates, 30-g daily consumption of dietary fiber was related to a lower risk of lung cancer (fourth vs first quartile OR: 0.62, 95 % CI: 0.54-0.72) compared with 8.8-g. Furthermore, consuming whole grains 2.3 servings per day as opposed to 0.3 servings per day was associated with a lower risk of lung cancer (OR: 0.73, 95 % CI: 0.64-0.83). A higher risk of lung cancer was seen for the consumption of high-GI food (OR: 1.19, 95 % CI: 1.05?1.35) and refined carbohydrates from soft drinks (OR: 1.23, 95 % CI: 1.04?1.46). Conclusion: Carbohydrates and fiber from fruits, vegetables and whole grains are associated with lower lung cancer risk. Refined carbohydrates from processed food, such as soft drinks, appear to increase risk.

An efficient and green protocol for aerobic oxidation of benzylic alcohols in ethanol using Cu-I-Y zeolite catalysts assisted by TEMPO (TEMPO = 2,2,6,6-tetramethyl-1-piperidine-N-oxyl) as the radical co-catalyst in the presence of atmospheric air under mild conditions is reported. The Cu-I-Y zeolite prepared via ion exchange between CuCl and HY zeolite was fully characterized by a variety of spectroscopic techniques including XRD, XPS, SEM, EDX and HRTEM. The incorporation of Cu(i) into the 3D-framework of the zeolite rendered the catalyst with good durability. The results of repetitive runs revealed that in the first three runs, there was hardly a decline in activity and a more substantial decrease in yield was observed afterwards, while the selectivity remained almost unchanged. The loss in activity was attributed to both the formation of CuO and the bleaching of copper into the liquid phase during the catalysis, of which the formation of CuO was believed to be the major contributor since the bleaching loss for each run was negligible (<2%). In this catalytic system, except TEMPO, no other additives were needed, either a base or a ligand, which was essential in some reported catalytic systems for the oxidation of alcohols. The aerobic oxidation proceeded under mild conditions (60 degrees C, and 18 hours) to quantitatively and selectively convert a wide range of benzylic alcohols to corresponding aldehydes, which shows great potential in developing green and environmentally benign catalysts for aerobic oxidation of alcohols. The system demonstrated excellent tolerance against electron-withdrawing groups on the phenyl ring of the alcohols and showed sensitivity to steric hindrance of the substrates, which is due to the confinement of the pores of the zeolite in which the oxidation occurred. Based on the mechanism reported in the literature for homogenous oxidation, a mechanism was analogously proposed for the aerobic oxidation of benzylic alcohols catalysed by this Cu(i)-containing zeolite catalyst.

Ketones are of great importance in synthesis, biology, and pharmaceuticals. This paper reports an iridium complexes-catalyzed cross-coupling of alcohols via hydrogen borrowing, affording a series of alpha-alkylated ketones in high yield (86 %-95 %) and chemoselectivities (>99 : 1). This methodology has the advantages of low catalyst loading (0.1 mol%) and environmentally benign water as the solvent. Studies have shown the amount of base has a great impact on chemoselectivities. Meanwhile, deuteration experiments show water plays an important role in accelerating the reduction of the unsaturated ketones intermediates. Remarkably, a gram-scale experiment demonstrates this methodology of iridium-catalyzed cross-coupling of alcohols has potential application in the practical synthesis of alpha-alkylated ketones.

Herein, we report a simple, efficient, and sustainable method for the synthesis of alpha-alkylated ketones and quinolines using a hydrogen-borrowing strategy, which has emerged as a greener alternative in organic transformation reactions. Synthesis of a range of alpha-alkylated ketones and quinoline derivatives was achieved by using the water-soluble [Ru(8-AQ)Cl(p-cym.)]Cl-+(-) [Ru]-1 (AQ=aminoquinoline) catalyst with water as the reaction medium. By adopting this strategy, we have synthesized alpha-alkylated ketones and quinolines using ketones or secondary alcohols as starting materials and the primary alcohol as a green and naturally abundant alkylating agent.
