Highly functionalized cyclopentanes with four stereogenic carbons including two quaternary stereocenters have been synthesized in excellent yields (90-95%) with complete diastereoselectivities and excellent enantioselectivities (88-96% ee) by the organocatalyzed asymmetric domino Michael-Henry reaction.
