10-(Methoxyimino)phenanthrene-9-one 1 reacts thermally with the arylacetic derivatives 2(a-j) to yield the corresponding 1,4-benzoxazin-2-ones 4(a-d,f) and benzo[d]oxazoles 5(a-e,g). Similarly, reaction of the monoximes 7a, 7b with compounds 2a, 2d respectively affords 8a, 8b, while action of trans-stilbene on the monoximes 1, 7a, 7b leads to the 1,4-benzoxazines 10, 11, 13, obtained along with the
10-(甲氧基亚氨基)菲-9-酮1下热与arylacetic衍生物进行反应2(AJ),得到相应的1,4-苯并恶嗪-2-酮4(广告,F)和苯并[ d ]恶唑-5(AE, g)。类似地,monoximes的反应7a,图7b用化合物2A,图2d分别得到图8A,8B,而动作反式对monoximes芪1,7A,7B通向1,4-苯并恶嗪10,11,13,而获得沿与相应的2-苯基恶唑5a,8a,8c和化合物12。
