Abstract

Intermolecular hydroalkoxylation of N-allenyl sulfonamides with oximes is achieved under mild gold(I)-catalyzed conditions delivering allyloximino E-enesulfonamides stereoselectively in moderate to high yields. The products contain two important functionalities, imines and enesulfonamides, within one framework containing an oxygen bridge, and the reaction is made possible via a convenient method for conjugated N-sulfonyliminium formation.
