Iodine(III)-Mediated Tandem Acetoxylation−Cyclization of o-Acyl Phenols for the Facile Construction of α-Acetoxy Benzofuranones
摘要:
An efficient tandem acetoxylation-cyclization of o-acylphenols mediated by the combination of iodobenzene diacetate with tetrabutylammonium iodide provides a new convenient and useful route to alpha-acetoxy benzofuranones.
