O-iodoxy benzoic acid–mediated synthesis of 3,5-diarylisoxazoles and isoxazole-3-carboxylic acids

Desai, Vidya G.,Naik, Sneha R.,Dhumaskar, Kashinath L.

, p. 1453 - 1460 (2016/09/23)

A new, convenient, ecofriendly synthesis of 3,5-diarylisoxazoles is reported from a,b-unsaturated ketoximes. Similarly, a novel synthesis of isoxazole carboxylic acids is also reported. Both the methods use efficient, environmentally friendly, and nontoxic iodoxybenzoic acid (IBX) as an oxidative cyclizing reagent. Easy procedure, environmentally benign reaction conditions, and nontoxicity are advantages to the methodology.
