Abstract
dro-2H-1,2-oxazolo[5,4-h]1,4-benzoxazin-6(6aH)-ons 5a-c were obtained by the reaction of hydroxyethylamino-1,4-benzoquinones 2a-c with nitri le oxide 3. The structures of the cycloadducts were elucidated NMR tec hniques including inverse longe-range C-13,H-1-experiments and homonuc lear NOE difference spectroscopy.
