Asymmetric Michael addition reactions catalyzed by calix[4]thiourea cyclohexanediamine derivatives
A number of upper rim-functionalized calix[4]thiourea cyclohexanediamine derivatives have been designed, synthesized and used as catalysts for enantioselective Michael addition reactions between nitroolefins and acetylacetone. The optimal catalyst 2 with a mono-thiourea group exhibited good performa...
