Organocatalyzedcascadereactions between cyclicβ-enaminoesters and α,β-unsaturatedaldehydes have been developed. They provide highly substituted indolo[2,3-a]quinolizidines and benzo[a]quinolizidines in moderate to good yields and with good to excellent enantioselectivities. Both aromatic and aliphatic α,β-unsaturatedaldehydes react readily with enamino esters to furnish the desired products.
