  Asymmetric dihydroxylation of 1-acyloxy-2(E)-alkenylphosphonates with AD-mix reagents. Effects of 1-acyloxy functional groups on the asymmetric dihydroxylation

  摘要：

  Asymmetric dihydroxylation (AD) of a racemic mixture of 1-acyloxy-2(E)-alkenylphosphonates with AD-mix-alpha or -beta reagents was examined. The kinetic rate of dihydroxylation was highly dependent upon the configuration of the 1-acyloxy functional group as well as the nature of substituents at the 3-position. ?he reaction of a racemic mixture of diethyl (E)-3-phenyl-1-acetyloxy-2-propenylphosphonate with an AD-mix-beta reagent preferentially dihydroxylated the R-enantiomer to leave an unreacted S-enantiomer of high enantiomeric purity. Double diastereoselection of the resolved diethyl 3-phenyl-1-acetyloxy-2(E)-propenylphosphonate in dihydroxylation was also examined. (C) 1997 Elsevier Science Ltd. All rights reserved.

• Kinetic resolution of hydroxyalkanephosphonates catalyzed by Candida antarctica lipase B in organic media

  A series of hydroxyalkanephosphonates were studied as substrates for CALB catalyzed acetylation with emphasis on enantioselectivity and chemical structure of substrates. Some hydroxyalkanephosphonates could be resolved successfully to give both (R)- and (S)-isomers with high enantiomeric excess.

  研究了一系列羟基链烷膦酸酯作为CALB催化乙酰化反应的底物，重点是底物的对映选择性和化学结构。一些羟基链烷膦酸酯可以成功地拆分，以得到具有高对映体过量的（R）-和（S）-异构体。

  日期：2003.6.1

  Enzymatic kinetic resolution of alpha- and beta-hydroxyphosphonates in combination with ruthenium-catalyzed alcohol isomerization led to a successful dynamic kinetic resolution. A variety of racemic hydroxyphosphonates were efficiently transformed to the corresponding enantiomerically pure acetates (ee up to 99% and yield up to 87%).
