Synthesis of some new 2-(3-aryl-1-phenyl-4-pyrazolyl)-benzoxazoles using hypervalent iodine mediated oxidative cyclization of Schiff's bases.
Ten new 2-(3-aryl-1-phenyl-4-pyrazolyl)benzoxazoles have been synthesized by oxidative intramolecular cyclization of the corresponding Schiff's bases using iodobenzene diacetate in methanol as an oxidant.
