An asymmetric synthesis of 3-formyl-1,4-dihydropyridines is described that entails the addition of organocopper reagents to activated 3-imidazolidinylpyridine, prepared with chiral diamines. The activator can be a chloroformate or an acid chloride. The methodology was used for the asymmetric syntheses of the indoloquinolizine and benzoquinolizine alkaloid frameworks.
