摘要:
A method for the synthesis of 2-substituted N,N'-diacylimidazolidines was developed. The method is based on the reactions of acylating reagents (carboxylic acid chlorides and anhydrides. sulfonic acid chlorides, a carbamic acid chloride, and ethyl chlorocarbonate) with Schiff's bases prepared by the reaction of N-acylethylenediamines with aldehydes.
