ABSTRACT
A copper-catalyzed sulfonylation of alkynyl imines with sulfonyl hydrazides has been developed, which exhibited excellent regio- and stereoselectivity and furnished a series of (E)-ß-sulfonyl enones in moderate to good yields. Mechanistic studies suggest that this strategy goes through a radical process.
