Abstract
An intramolecular organocatalytic enantioselective aza-Michael reaction of carbamates, sulfonamides and acetamides to α,β-unsaturated ketones was developed. This process is promoted by 9-amino-9-deoxy-epi-quinine and diphenyl hydrogen phosphate to afford a straightforward and expeditious synthesis of several synthetically useful five- and six-membered heterocycles with excellent enantioselectivity (92%–97.5% ee) and very good yields (up to 99%).
