摘要

A convenient and regioselective sulfonylation/cyclization of 1,6-enynes with arylazo sulfones has been developed to access a series of sulfonylated γ-butyrolactams. The present reaction could be efficiently conducted under catalyst-and additive-free conditions, in which C--S and C--C bonds were selectively constructed in one-pot procedure.
