摘要：
Treatment of allylic esters such as allyl benzoate (3a), allyl phenylacetate (4), allyl 3-phenylpropanoate (5), crotyl esters 14, 4-bromo-2-butenyl esters 15, and 1,4-bis(aroyloxy)-2-butenes 16 with NOBF4 in CH3CN at -23 degrees C gave alkanoyloxy (or aroyloxy)-2-isoxazolines and 3-substituted 4-alkanoyloxy (or aroyloxy)-2-isoxazolines, depending on the allylic esters.
