An organocatalytic enantioselective direct vinylogous allylic alkylation between coumarins and racemic Morita- Baylis-Hillman carbonates has been developed. With 10~15 mol% a chiral cyclohexane-based phosphine-amide C10, a wide range of densely functionalized coumarin derivatives have been achieved in 87%~99% yields and up to 98% ee.

Key words: allylic alkylation, asymmetric catalysis, chiral phosphine, organocatalysis, vinylogous reaction
