A novel enzymatic, promiscuous protocol for Candida antarctica lipase B (CAL-B)-catalyzed carbon-sulfur bond addition is described. Some control experiments have been designed to demonstrate the catalytic specificity of CAL-B. Selectivity between anti-Markovnikov addition and Markovnikov addition was achieved in different organic media. A series of thioether-containing ester functional groups was synthesized
描述了一种新型的酶促混合方案,用于南极假丝酵母脂肪酶B(CAL-B)催化的碳硫键加成。设计了一些对照实验来证明CAL-B的催化特异性。在不同的有机介质中实现了反马尔科夫尼科夫加法和马尔科夫尼科夫加法之间的选择性。在CAL-B催化下于50°C合成了一系列含硫醚的酯官能团。所有产物均通过光谱法(IR,NMR,ESI-MS)表征。
