Synthesis of tertiary amines containing gem-dichlorocyclopropane and cycloacetal fragments

Abstract

Reactions of secondary amines containing gem-dichlorocyclopropane and cycloacetal fragments with allyl chloride, trans-1,3-dichloropropene, benzyl chloride, and chloromethyl-gem-dichlorocyclopropane were studied. The corresponding tertiary amines were obtained in 20–85% yield. Microwave radiation stimulates N-alkylation of the secondary amine containing the heterocyclic moiety. The structures of the tertiary amines prepared were studied. The configuration of the double bond in the trans-1,3-dichloropropene derivative is retained.
