Preparation of 2,3,4,5-Tetrahydropyridines from 5-Alkynylamines Under the Catalytic Action of Gold(III) Salts

Abstract

Intramolecular addition of amine to carbon-carbon triple bonds in 5-alkynylamines produces 2,3,4,5-tetrahydropyridines under the catalytic action of an aurate salt. Some venom components of various ant species are synthesized by the application of this reaction.
