Asymmetric intramolecular Michael addition of α-sulfinyl vinylic carbanion to enoates

The first example of an asymmetric intramolecular Michael addition reaction with use of α-lithiated vinylic sulfoxide as a Michael donor is reported. Michael addition of the α-lithiated vinylic sulfoxide to (Z)-enoates proceeds with high diastereoselectiv

Highly stereoselective intramolecular Michael addition using α-sulfinyl vinyllithium as an unprecedented Michael donor
