The organocatalytic enantioselective anti-Michael addition uses a sulfone as directing group of the regioselectivity and as a leaving group in the same reaction. These prop-erties allow the creation of α,α'-branched terminal double bond joined to a quaternary center. — (ALEMAN, J.; REYES, E.; RICHTER, B.; OVERGAARD, J.; JOERGENSEN*, K. A.; Chem. Commun.
