Enantioselective Synthesis of Indoloquinolizidines. Key words: Chiral 1,4-dihydropyridines - chiral symmetrical diamines - chiral indoloquinolizidines.

Asymmetric synthesis of indoloquinolizidine has been accomplished by using acyl pyridinium salt bearing in 3 position a chiral aminal.

Preparation and utilization of chiral dihydropyridines. Synthesis of chiral indoloquinolizines and benzoquinolizines

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 m
