Abstract

Organocopper reagents react with 1-acylpyridinium salts, bearing in the 3 position a chiral aminal [1-acyl-3-(trans-1,3-dimethyl-4, 5-diphenylimidazolidin-2-yl)pyridinium salts], to give after acidic hydrolysis chiral 4-substituted 1-acyl-1, 4-dihydropyridine-3-carboxaldehydes in high optical purity and in good chemical yield.
