    Diastereoconvergent Negishi Cross-Coupling Using Functionalized Cyclohexylzinc Reagents
    摘要:
    Highly diastereoselective Pd-catalyzed cross-coupling reactions of functionalized 2-, 3-, and 4-substituted cyclohexylzinc reagents with aryl, heteroaryl, and alkenyl iodides have been performed under mild conditions. The use of Ruphos (2-dicyclohexylphosphino-2',6'-diisopropoxybiphenyl) as a ligand as well as LiCl and N-ethylpyrrolidone (NEP) as additives leads to especially high diastereoselectivities and displays good functional group tolerance. The stereoselectivity can be explained by assuming that the intermediate palladium moiety occupies an equatorial position of the cyclohexyl ring.

  • Efficient α-Methylenation of Carbonyl Compounds in Ionic Liquids at Room Temperature
    作者:J. Rodrigues、Juliana Vale、Daniel Zanchetta、Paulo Moran
    DOI:10.1055/s-0028-1087389
    日期:——
    The application of several 1-butyl-3-methylimidazolium (BMIM) salt ionic liquids as solvent in the α-methylenation of carbonyl compounds at room temperature is reported. The ionic liquid [BMIM][NTf2] gave a clean reaction in a short time and good yields of several α-methylene carbonyl compounds. This ionic liquid was reused without affecting the reaction rates or yields over seven runs.

    The post-translational modification (PTM) and signaling molecule poly(ADP-ribose) (PAR) has an impact on diverse biological processes. PTM is regulated by a series of ADP-ribosyl glycohydrolases (PARG enzymes) that cleave polymers and/or liberate monomers from their protein targets. Disclosed herein is a substrate for monitoring PARG activity, TFMU-ADPr, which directly reports on total PAR hydrolase activity via release of a fluorophore; this substrate has excellent reactivity, generality, stability, and usability. A second substrate, TFMU-IDPr, selectively reports on PARG activity only from the enzyme ARH3. Use of these probes in whole-cell lysate experiments has revealed a mechanism by which ARH3 is inhibited by cholera toxin. TFMU-ADPr and TFMU-IDPr are versatile tools for assessing small-molecule inhibitors in vitro and probing the regulation of ADP-ribosyl catabolic enzymes.
    翻译结果:翻译后修饰(PTM)和信号分子聚腺苷二磷酸核糖(PAR)对多种生物过程产生影响。PTM受一系列ADP核糖水解酶(PARG酶)调控,这些酶从它们的蛋白靶标中切割聚合物和/或释放单体。本文披露了一种用于监测PARG活性的底物,TFMU-ADPr,它通过释放荧光团直接报告总PAR水解酶活性;该底物具有出色的反应性、普适性、稳定性和可用性。第二种底物TFMU-IDPr,只选择性地报告来自酶ARH3的PARG活性。在全细胞裂解液实验中使用这些探针揭示了一种由霍乱毒素抑制ARH3的机制。TFMU-ADPr和TFMU-IDPr是评估体外小分子抑制剂和探究ADP核糖降解酶调控的多功能工具。

The substrates were prepared by Wittig or Peterson olefination of carbonyl compounds which were in turn generated by conjugate addition of thiophenol or of the cuprate of a phenylthio-stabilized carbanion to an α,β-unsaturated carbonyl compound.

    transformation of enones was investigated with cultured cells of Synechococcus sp. PCC 7942 (a cyanobacterium). The cells reduced both the endocyclic C-C double bond of s-trans enones and the exocyclic C-C double bond of s-cis enones with high enantioselectivity to afford optically active α-substituted (S)-ketones under illumination. In addition, the reduction of the double bond of these enones was accompanied
