A chemoenzymatic methodology has been developed using indium-mediated allylation of heterocyclic aldehydes under aqueous conditions followed by Pseudomonas cepacia lipase-catalyzed enantioselective acylation of racemic homoallylic and homopropargylic alcohols in organic media. It is observed that the lipase immobilized on ceramic particles (PS-C Amano II) catalyzes the resolution in a highly enantioselective
已开发出一种化学酶学方法,该方法是在水性介质中使用铟介导的杂环醛的烯丙基化烯丙基化,然后在有机介质中假单胞菌cepcia脂肪酶催化外消旋均烯丙基和均炔丙醇的对映选择性酰化。观察到,与天然酶(PS Amano)相比,固定在陶瓷颗粒上的脂肪酶(PS-C Amano II)以更少的时间以高对映选择性的方式催化拆分。该方法提供了新的功能化手性合成子,可用于合成天然和假天然产物。
