Abstract

A process for preparing α-functionalized thiazolidines or oxazolidines, each of which are oxycarbonyl-functionalized in the 4-position, by adding a base to a reaction mixture comprising an oxycarbonyl-functionalized thiazolidine or oxazolidine and an electrophile at a temperature of greater than −40° C.
