A highly enantioselective (S) diphenylpyrrolinol silyl ether promoted tandem Michael-aldol reaction of alpha,beta-unsaturated aldehydes with 2-mercaptobenzaldehydes has been developed. The method affords one-pot access to chiral and synthetically useful thiochromenes in high yields and high enantioselectivities from readily available compounds.
已开发出高度对映选择性 (S) 二苯基吡咯啉甲硅烷基醚促进 α、β-不饱和醛与 2-巯基苯甲醛的串联迈克尔-羟醛反应。该方法提供了从容易获得的化合物中以高产率和高对映选择性获得手性和合成有用的硫色素的一锅法。
