ChemInform Abstract: Iodobenzene‐Mediated Intramolecular Oxidative Coupling of Substituted 4‐Hydroxyphenyl‐N‐phenylbenzamides for the Synthesis of Spirooxindoles.

Abstract

A series of spirooxindoles (II) is readily prepared by an intramolecular oxidative coupling reaction of benzamides (I). The analogous reaction of amides (VI) gives rise to spirodihydroquinolones (VII) in moderate yields. -(YU, Z.; JU, X.; WANG, J.; YU*, W.; Synthesis 2011, 6, 860-866, http://dx.
