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

摘要

The reactions of l,2,3,7a-tetrahydroimidazo[1,2-6]isoxazole derivatives with electrophilic reagents,such as protic acids,benzoyl chloride,BF3,and bromine,produce isoxazole,2,2,3,3-tetramethylaziridine,and 2,3,3-trimethylpropen-2-ylamine derivatives.
