Dehydrogenative cycloisomerization-arylation reaction of N-propargyl carboxamides by iodine(III)-catalysis using activated sulfoxide
Abstract
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 of inexpensive reagents and is applicable to a wide range of aromatic compounds.
