Abstract

Dilithiated amides (2), derived from N-phenyl or N-methylacetamide and n-BuLi, react with 3-cyanopyridine (1a), 3-(1,3-oxazol-2-in-2-yl)pyridine (1b) or 3-(4,4-dimethyl 1,3-oxazol-2-in-2yl)pyridine (1c) to give dihydropyridines. The major isomer obtained in each case is the 1,6-dihydropyridine (3a-f).
