文摘
A one-pot [3 + 2] cycloadditive synthesis of benzo[d]isoxazole-4,7-diols in aqueous medium was carried out via nitrile oxides and benzoquinone intermediates by taking advantage of iodobenzene diacetate as an oxidant. This method can also be used to synthesize benzodiisoxazole-4,8-diols, isoxazolo[5,4-a]phenazines, and indazole-4,7-diols, which are difficult to obtain by classical methods.
