  名称：

  Highly regioselective lipase-catalyzed acetylation and hydrolysis of acyclic α,α′-alkenediols and their diacetates

  摘要：

  Highly regioselective transformation of acyclic alpha,alpha'-alkenediols and their corresponding diacetates to monoacetates using lipase was accomplished. The acetylation of the alpha,alpha'-alkenediol regioselectively gave (E)-monoacetate, whereas the (Z)-monoacetate were obtained by hydrolysis of the alpha,alpha'-diacetate. (c) 2005 Elsevier Ltd.

• A Convenient Synthesis of the (<i>E</i>)-Monoacetates of 2-Alkylidenepropane-1,3-diols

  日期：2008.9

  Various kinds of 3-substituted (E)-2-(hydroxymethyl)prop-2-enyl acetates were conveniently obtained in excellent yields by the regiospecific acetylation of 2-alkylidenepropane-1,3-diols with 10 equivalents of vinyl acetate in the presence of 50% w/w porcine pancreatic lipase (PPL) type II; the starting materials or (Z)-monoacetate or diacetate byproducts were generally not present.

  通过在50% w/w的猪胰脂肪酶（PPL）II型存在下，用10等摩尔的乙烯醋酸酯对2-烷基烯丙基-1,3-二醇进行区域特异性醋酸酯化，可以方便地获得各种3-取代的(E)-2-(羟甲基)丙-2-烯基醋酸酯，且收率极高；起始材料或(Z)-单醋酸酯或双醋酸酯副产物一般不存在。
