  Lipase-catalyzed kinetic resolution of (RS)-hydroxy tellurides

  摘要：

  The enzymatic resolution of racemic mixtures of hydroxy tellurides with a range of lipases has been investigated. Lipase-B from Candida antarctica (CALB) gave the best conversions, providing both enantiomers with high enantiomeric purity. A comparative study of the effect of solvent and substrate on the enzymatic kinetic resolution was performed. (c) 2006 Elsevier Ltd. All rights reserved.

  described in which a Michael addition of an alkyl or aryl tellurolate anion occurs onto an activated alkyne with subsequent trapping of a vinyl anion with electrophiles (aldehydes and ketones) other than a proton. This process provides an efficient regio- and stereospecific route to tri- and tetrasubstituted alkenes. Methodologically significant examples of this chemistry were studied in which aryl and alkyl

  描述了一种新颖的电遥测方法，其中烷基或芳基碲酸根阴离子的迈克尔加成发生在活化的炔上，随后用质子以外的亲电子试剂（醛和酮）捕获乙烯基阴离子。该方法为三和四取代的烯烃提供了有效的区域和立体有择途径。研究了该化学方法学上的重要实例，其中在迈克尔反应中将芳基和烷基碲酸根阴离子添加到ω-酮炔基酯中，初始乙烯基阴离子被内部醛分子内捕获。反应中心被不同长度的烷基链束缚，以适度到良好的产率形成高度官能化的五，六，七和八元环。

  stable, nonhygroscopic, and readily available chiral derivatizing agent (CDA) for NMR chiral discrimination of chalcogen containing secondary alcohols. The chiral recognition by CDA and chiral solvating agent (CSA) was assessed using 1H, 77Se‐1H}, and 125Te‐1H} NMR spectroscopy. A simple model for the assignment of the absolute configuration from NMR data is presented.
