Abstract

A convenient method for obtaining pyridine alkaloid cerpegin and its various new C-1 and N-5 derivatives in high yields has been developed. Starting enaminolactones, synthesized by means of various tertiary keto-alcohols, have been condensed with primary aliphatic, aromatic or heterocyclic amines for a pyridine cycle formation. Bromine derivatives of furo[3,4-c]pyridinenones are obtained as well.
