Dehydrogenative cycloisomerization-arylation reaction of N-propargyl carboxamides by iodine(III)-catalysis using activated sulfoxide

We herein describe a dehydrogenative cycloisomerization-arylation reaction of N-propargyl carboxamides with aromatic compounds by hypervalent iodine(III)-catalysis using sulfonyl chloride and sulfoxide. Compared to conventional methods, this approach allows the use...
