Esterification in an aqueous micellar medium is catalyzed by a commercially available lipase in the absence of any co-factors. The presence of only 2 wt% designer surfactant, TPGS-750-M, assists in a 100% selective enzymatic process in which only primary alcohols participate (in a 1 : 1 ratio with carboxylic acid). An unexpected finding is also disclosed where the simple additive, PhCF (1 equiv. substrate), appears to significantly extend the scope of usable acid/alcohol combinations. Taken together, several chemo- and bio-catalyzed 1-pot, multi-step reactions can now be performed in water.
在水性胶束介质中,市售脂肪酶在无任何辅助因子的情况下催化酯化反应。仅2 wt%的定制表面活性剂TPGS-750-M的存在有助于实现100%选择性的酶促过程,其中只有伯醇参与反应(与羧酸的比例为1∶1)。还公开了一个意外发现,即简单添加剂PhCF(1当量底物)似乎能显著扩展可用酸/醇组合的范围。综上所述,现在可以在水中进行几种化学催化和生物催化的一锅多步反应。
