以2-吡咯基三氯乙酮为主要原料,经过乙二醇单酯化、羟基氯取代、环合三步反应制得了3,4-二氢吡咯[2,1-c][1,4]噁嗪-1-酮;又经过Friedel-Crafts酰基化和环合反应制得了未见文献报道的7-芳酰基-3,4-二氢吡咯[2,1-c][1,4]噁嗪-1-酮.它们及其某些重要中间体的结构分别采用红外光谱、质谱、核磁共振氢谱、核磁共振碳谱以及高分辨率质谱进行了表征.
Using 2-pyrrolyltrichloroethanone as the main raw material, 3,4-dihydropyrrolo [2,1-c] [1,4 ] Oxazin-1-one. After Friedel-Crafts acylation and cyclization reaction, 7-aroyl-3,4-dihydropyrrolo [2,1-c] Oxazin-1-one.The structures of them and some of their important intermediates were characterized by IR, MS, 1H NMR, 13C NMR and high resolution mass spectrum respectively.
