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, Wei;Tang, Weng Lin;Wang, Zunsheng;Li, Zhi research published 《 Regio- and Stereoselective Biohydroxylations with a Recombinant Escherichia coli Expressing P450_pyr Monooxygenase of Sphingomonas Sp. HXN-200》, the research content is summarized as follows. A recombinant Escherichia coli expressing P 450_pyr monooxygenase of Sphingomonas sp HXN-200 was developed as a useful biocatalyst for regio- and stereoselective hydroxylations, with no side reaction and easy cell growth. The resting E. coli cells showed an activity of 4.1 U/g cdw and 9.9 U/g cdw for the hydroxylation of N-benzylpyrrolidin-2-one and N-benzyloxycarbonylpyrrolidine, resp., being as active as the wide-type strain. Biohydroxylation of N-benzylpyrrolidin-2-one 1 with the resting cells gave (S)-N-benzyl-4-hydroxypyrrolidin-2-one in >99% ee and 10.8 mM, a 2.6 times increase of product concentration in comparison with the wild-type strain. Biohydroxylation of N-tert-butoxycarbonylpiperidin-2-one, N-benzylpiperidine and N-tert-butoxycarbonylazetidine with the E. coli cells afforded the corresponding 4-hydroxypiperidin-2-one, 4-hydroxypiperidine, and 3-hydroxyazetidine in 14 mM, 17 mM, and 21 mM, resp. Moreover, hydroxylation of (-)-β-pinene with the recombinant E. coli cells showed excellent regio- and stereoselectivity and gave (1R)-trans-pinocarveol in 82% yield and 4.1 mM, which is over 200 times higher than that obtained with the best biocatalytic system known thus far.

Aldehyde dehydrogenases (ALDHs) metabolize reactive aldehydes and possess important physiol. and toxicol. functions in areas such as CNS, metabolic disorders, and cancers. Increased ALDH (e.g., ALDH1A1) gene expression and catalytic activity are vital biomarkers in a number of malignancies and cancer stem cells, highlighting the need for the identification and development of small mol. ALDH inhibitors. A new series of theophylline-based analogs as potent ALDH1A1 inhibitors is described. The optimization of hits identified from a quant. high throughput screening (qHTS) campaign led to analogs with improved potency and early ADME properties. This chemotype exhibits highly selective inhibition against ALDH1A1 over ALDH3A1, ALDH1B1, and ALDH2 isoenzymes as well as other dehydrogenases such as HPGD and HSD17β4. Moreover, the pharmacokinetic evaluation of selected analog (NCT-501) is also highlighted.

Yu, Liyang;Zhang, Meiling;Tang, Jie;Li, Ruipeng;Xu, Xiaopeng;Peng, Qiang research published 《 Wide Bandgap Perylene Diimide Derivatives as an Effective Third Component for Parallel Connected Ternary Blend Polymer Solar Cells》, the research content is summarized as follows. Constructing a ternary blend active layer for polymer solar cells (PSCs) is a widely explored approach to achieve a high power conversion efficiency (PCE). To achieve this, multiple approaches have been explored for dual-acceptor PSCs including acceptor alloy and acceptor cascade. Parallel connection is another working mechanism of ternary blends with the advantage of large freedom in the selection of materials with largely different absorption ranges. Here, we purposely designed two propeller-like perylene diimide (PDI) derivatives, TT-PDI and TZ-PDI, with different central cores and selected one as the third component to be added into a PM6:Y6 blend. The highest PCE of 17.52% was obtained with 10% of Y6 replaced by TZ-PDI in the ternary blend. To our knowledge, this is the first report of a PDI derivative to be added into a PM6:Y6 blend with significantly increased device performance. The improved PCE was ascribed to the high photon absorption due to the wide bandgap and amorphous structure of TZ-PDI, which paved a functional parallel charge generation route without interfering with the nanostructure of the PM6:Y6 blend. This work demonstrated the parallel connected ternary blend as a viable route to construct efficient PSCs and a chem. designing strategy for a suitable third component in ternary blends.

Yuan, Jinping;Jain, Pankaj;Antilla, Jon C. research published 《 Bi(cyclopentyl)diol-Derived Boronates in Highly Enantioselective Chiral Phosphoric Acid-Catalyzed Allylation, Propargylation, and Crotylation of Aldehydes》, the research content is summarized as follows. In this study, we disclose the catalytic addition of bi(cyclopentyl)diol-derived boronates to aldehydes promoted by chiral phosphoric acids such as (R)-TRIP-PA, allowing for the formation of enantioenriched homoallylic, propargylic, and crotylic alcs. (up to >99% enantiomeric excess (ee), diastereomeric ratio (dr) >20:1). These boronate substrates provided superior enantioselectivities, allowing for the reactions to proceed with low catalyst loading (0.5-5 mol %) and reduced reaction time (15 min at room temperature for aldehyde allylboration). A wide substrate scope was exhibited, and the novel boronates provided high enantiocontrol. Reactions with substituted allylboronates and aldehydes yielded vicinal stereogenic alcs. bearing β-tertiary or quaternary carbon centers. High enantio- and diastereoselectivities were found due to the closed six-membered chair-like transition state, with backbone modifications of the boronate and its interactions with the chiral phosphoric acid being the most likely contributing factor.

Vascular adhesion protein-1 (VAP-1) is a promising therapeutic target for the treatment of diabetic nephropathy. Here, the authors conducted structural optimization of the glycine amide derivative (I), which the authors previously reported as a novel VAP-1 inhibitor, to improve stability in dog and monkey plasma, and aqueous solubility By chem. modification of the right part in the glycine amide derivative, the authors identified the carbamimidoylcarbamate derivative, which showed stability in dog and monkey plasma while maintaining VAP-1 inhibitory activity. The authors also found that conversion of the pyrimidine ring in the derivative into saturated rings was effective for improving aqueous solubility This led to the identification of two moderate VAP-1 inhibitors with excellent aqueous solubility Further optimization led to the identification of 2-fluoro-3-{3-[(6-methylpyridin-3-yl)oxy]azetidin-1-yl}benzyl carbamimidoylcarbamate (II), which showed similar human VAP-1 inhibitory activity to I with improved aqueous solubility II showed more potent ex vivo efficacy than I, with rat plasma VAP-1 inhibitory activity of 92% at 1 h after oral administration at 0.3 mg/kg. In the pharmacokinetic study, II showed good oral bioavailability in rats, dogs, and monkeys, which may be due to its improved stability in dog and monkey plasma.
