Zhang, Zhenhua;Gorski, Bartosz;Leonori, Daniele research published 《 Merging Halogen-Atom Transfer (XAT) and Copper Catalysis for the Modular Suzuki-Miyaura-Type Cross-Coupling of Alkyl Iodides and Organoborons》, the research content is summarized as follows. A mechanistically distinct approach to achieve Suzuki-Miyaura-type cross-couplings between alkyl iodides and aryl organoborons was reported. This process required a copper catalyst but, in contrast with previous approaches based on palladium and nickel systems, does not utilizes the metal for the activation of the alkyl electrophile. Instead, this strategy exploited the halogen-atom transfer ability of α-aminoalkyl radicals to convert secondary alkyl iodides into the corresponding alkyl radicals that then were coupled with aryl, vinyl, alkynyl, benzyl and allyl boronate species. These novel coupling reactions feature simple set up and conditions (1 h at room temperature) and facilitate access to privileged motifs targeted by the pharmaceutical sector.

Application In Synthesis of 141699-55-0, Tert-butyl 3-hydroxyazetidine-1-carboxylate is a useful research compound. Its molecular formula is C8H15NO3 and its molecular weight is 173.21 g/mol. The purity is usually 95%.

Tert-butyl 3-hydroxyazetidine-1-carboxylate has been shown to be a good substrate for the preparation of N-protected amino alcohols and amines by the process of reductive amination. In this synthesis, tert-butyl azetidinium chloride is used as a catalyst in the reaction with sodium hydroxide. The tert-butyl group can be removed using ammonium hydroxide in the presence of a base such as triethylamine. This reaction can be performed on a large scale, making it useful in the manufacture of pharmaceuticals. The efficiency and solubility of this process make it suitable for use as an introduction to other processes involving N-protected amino alcohols or amines., 141699-55-0.

Formula: C9H17BO2, Allylboronic acid pinacol ester is a useful research compound. Its molecular formula is C9H17BO2 and its molecular weight is 168.04 g/mol. The purity is usually 95%.
Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., 72824-04-5.

Zhang, Zhi-Qi;Sang, Yue-Qian;Wang, Cheng-Qiang;Dai, Peng;Xue, Xiao-Song;Piper, Jared L.;Peng, Zhi-Hui;Ma, Jun-An;Zhang, Fa-Guang;Wu, Jie research published 《 Difluoromethylation of Unactivated Alkenes Using Freon-22 through Tertiary Amine-Borane-Triggered Halogen Atom Transfer》, the research content is summarized as follows. The application of abundant and inexpensive fluorine feedstock sources to synthesize fluorinated compounds is an appealing yet underexplored strategy. Here, authors report a photocatalytic radical hydrodifluoromethylation of unactivated alkenes with an inexpensive industrial chem., chlorodifluoromethane (ClCF₂H, Freon-22). This protocol is realized by merging tertiary amine-ligated boryl radical-induced halogen atom transfer (XAT) with organophotoredox catalysis under blue light irradiation A broad scope of readily accessible alkenes featuring a variety of functional groups and drug and natural product moieties could be selectively difluoromethylated with good efficiency in a metal-free manner. Combined exptl. and computational studies suggest that the key XAT process of ClCF₂H is both thermodynamically and kinetically favored over the hydrogen atom transfer pathway owing to the formation of a strong boron-chlorine (B-Cl) bond and the low-lying antibonding orbital of the carbon-chlorine (C-Cl) bond.

Zhao, Wei-Cheng;Li, Rui-Peng;Ma, Chao;Liao, Qi-Ying;Wang, Miao;He, Zhi-Tao research published 《 Stereoselective gem-C,B-Glycosylation via 1,2-Boronate Migration》, the research content is summarized as follows. A novel protocol is established for the long-standing challenge of stereoselective geminal bis-glycosylations of saccharides. The merger of PPh₃ as a traceless glycosidic leaving group and 1,2-boronate migration enables the simultaneous introduction of C-C and C-B bonds at the anomeric stereogenic center of furanoses and pyranoses. The power of this method is showcased by a set of site-selective modifications of glycosylation products for the construction of bioactive conjugates and skeletons. A scarce metal-free 1,1-di-functionalization process of alkenes is also concomitantly demonstrated.

Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 141699-55-0, formula is C8H15NO3, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Category: alcohols-buliding-blocks

Bruton’s tyrosine kinase proteolysis-targeting chimeras (BTK-PROTACs) have emerged as a promising approach to address the limitations of BTK inhibitors. However, conducting the rational discovery of orally bioavailable BTK-PROTACs presents significant challenges. In this study, dimensionality reduction anal. and model mol. validation were utilized to identify some key structural features for improving the oral absorption of BTK-PROTACs. The results were applied to optimize the newly discovered BTK-PROTACs B1 and B2. Compound C13 (I) was discovered with improved oral bioavailability, high BTK degradation activity, and selectivity. It exhibited inhibitory effects against different hematol. cancer cells and attenuated the BTK-related signaling pathway. The oral administration of C13 effectively reduced BTK protein levels and suppressed tumor growth. This study led to the discovery of a new orally bioavailable BTK-PROTAC for the treatment of lymphoma, and we hope that the strategy will find wide utility.

A novel strategy for the preparation of ketones R¹C(O)CHR²CH₂CH₂R³ (R¹ = n-pentyl, cyclohexyl, Ph, 2-thienyl, 4-pyridinyl, etc., R² = R³ = H; R¹ = Ph, R² = Ph, 4-MeC₆H₄, 2-naphthyl, 3-furyl, etc., R³ = H; R¹ = Ph, R² = H, R³ = Et, Ph; etc.) from aldehydes R¹CHO and allylic boronic esters R²CH:CHCHR³Bpin is presented. This reaction involves the allylation of aldehydes with allylic boronic esters and the Rh-catalyzed chain-walking of homoallylic alcs. The key to this successful development is the protodeboronation of alkenyl boryl ether intermediate via a tetravalent borate anion species in the presence of KHF₂ and MeOH. This approach features mild reaction conditions, broad substrate scope, and excellent functional group tolerance. Mechanistic studies also supported that the tandem allylation and chain-walking process are involved.

A remote C(sp³)-H bond asym. borylation of unactivated alkenes was achieved by bimetallic relay catalysis.
