Substrate Controlled Synthesis of Benzisoxazole and Benzisothiazole Derivatives via PhI(OAc)(2)-Mediated Oxidation Followed by Intramolecular Oxidative O-N/S-N Bond Formation
A phenyliodine(III) diacetate (PIDA)-mediated, highly efficient and tandem approach for the synthesis of aryldiazenylisoxazolo(isothiazolo)arenes from simple 2-amino-N’-arylbenzohydrazides has been developed. The reaction proceeds via formation of (E)-(2=aminoaryl)-(aryldiazenyl)methanone as the key intermediate, followed by intramolecular oxidative O-N/S=N bond formation in one pot at room temperature. The quiet different reactivity of the substrate is due to the formation of a diazo intermediate which encounters a nucleophilic attack by carbonyl oxygen on the electrophilic amine to produce isoxazole products, as compared to the previous reports(1a,b,4) in which an N-acylnitrenium ion intermediate is intramolecularly trapped by an amine group.
