Regioselective Synthesis of Substituted Imidate N-[1-Methyleneisobenzofuran-3(1H)-ylidene]benzenamines via Palladium-Catalyzed Tandem Heteroannulation of o-(1-Alkynyl)benzamides with Iodobenzene

[摘要]：A variety of substituted imidate N-[1-methyleneisobenzofuran-3(1H)-ylidene]benzenamines have been prepared in good to excellent yields by the palladium-catalyzed tandem heteroannulation of o-(1-alkynyl)benzamides with iodobenzene. The products obtained from this process were unusual substituted N-[isobenzofuran-3(1H)-ylidene]benzenamines. The tandem cyclization of readily available o-(1-alkynyl)benzamides and aryl iodides provided a powerful tool for the preparation of functionally substituted N-[isobenzofuran-3(1H)-ylidene]benzenamine compounds.
