Synthesis of isoxazoles via electrophilic cyclization.

Jesse P Waldo1, Richard C Larock.   

Abstract

[reaction: see text] A variety of 3,5-disubstituted 4-halo(seleno)isoxazoles are readily prepared in good to excellent yields under mild reaction conditions by the reaction of 2-alkyn-1-one O-methyl oximes with ICl, I2, Br2, or PhSeBr.
