Transformation of 1,2,3,7a-tetrahydroimidazo[1,2-b]isoxazole derivatives into isoxazoles

Abstract

The reactions of 1,2,3,7a tetrahydroimidazo[1,2 b]isoxazole derivatives with electrophilic reagents, such as protic acids, benzoyl chloride, BF 3 , and bromine, produce isoxazole, 2,2,3,3 tetramethylaziridine, and 2,3,3 trimethylpropen 2 ylamine derivatives.
