Abstract

As an extension of the boron enolate-based aldol reactions, the oxazolidinone-installed bisimide from 3-(trifluoromethyl)glutaric acid was employed for Mannich reactions with tosylated imines as electrophiles to successfully obtain the corresponding adducts in a stereoselective manner.

摘要

作为基于硼烯醇盐的羟醛反应的扩展,由3-(三氟甲基)戊二酸制备的恶唑烷酮取代的双酰亚胺被用于与对甲苯磺酰化亚胺作为亲电试剂的曼尼希反应,以立体选择性方式成功获得相应的加合物。
