Process for preparing 2,2-disubstituted thiazolidines

摘要

A method for preparing 2,2-disubstituted thiazolidine involves reacting aminoalkyl hydrogen-sulfate with a compound having hydrosulfide ion in the presence of ketone. According to the present method, such thiazolidine can be prepared in good yield and desired purity without using harmful ethylenimine as a starting material.
