Abstract

Schiff bases derived from tryptamine react with Brassard's diene in the presence of EtAlCl2 to give functionalised 1,2,5,6-tetrahydropyridines which are subsequently transformed to indolo[2,3-a]quinolizines by Bischler-Napieralski reaction and reduction of the intermediate iminium salts with NaBH4.
