Abstract

Asymmetric intramolecular Michael reaction catalyzed by an organocatalyst derived from cysteine has been developed for the synthesis of chiral bicyclo [4.3. 0] nonene and cis- disubstituted cyclopentane skeletons with a creation of three or two contiguous chiral centers in good yield with high diastereo-and excellent enantioselectivities.
