Titanium enolates add to the 4-position of l-phenoxycarbonylpyridinium salts to give 1,4\_dihydropyridines; subsequent aromatization provides 4-(2-oxoalkyl)pyridines. Development of practical methods for directing nucleophiles to the 4-position of a pyridine ring has been a challenge to synthetic ch
