Enantioselective synthesis of coumarins catalyzed by a bifunctional amine-thiourea catalyst

Efficient excess: An efficient and facile enantioselective Michael addition reaction through hydrogen-bonding catalysis for the synthesis of coumarin complexes has been developed (see scheme). A simple bifunctional amine-thiourea small molecule has been discovered to catalyze this process with high yields and high to excellent enantiomeric excesses.
