Abstract
A new procedure for the selective reduction of conjugated Delta (2)-isoxazo lines to the corresponding unsaturated beta -hydroxy ketones is described. The use of SmI2 as the reducing agent and B(OH)(3) to hydrolyze the resulti ng imine results in a mild, convenient, and chemoselective protocol for thi s otherwise difficult transformation and complements existing methodology f or the preparation of beta -hydroxy ketones via nitrile oxides.
