Abstract

The iodobenzene-catalyzed oxidative cyclization of a δ-alkynyl β-ketoester has been investigated by density functional theory (DFT) calculations at the CPCM(acetonitrile)/B3LYP/6-311++G(d,p)//B3LYP/SDD(I) levels. Three different mechanisms were considered for this process, and of the three, activation of the alkyne by a hypervalent iodine species followed by cyclization was found to be the most likely pathway based upon our computational results.
