本文给出了一条较好的制备5-丁基-9-苯基-4,5,6,9-四氢苯并[d.e]吣唑[5,4-g]-异喹啉-4,6-二酮的反应路线,即:先由4-溴-1,8-萘酐经亚胺化、硝化、水解和还原等反应制得N-丁基-3-硝基-4羟基-1,8萘酰亚胺,再在硼酸的存在下,将亚胺与苯甲酰氯反应可得到目标化合物。文中给出了该化合物的质谱、核磁共振、红外、紫外和荧光等光谱数据。 This paper presents a better method for the preparation of 5-butyl-9-phenyl-4,5,6,9-tetrahydrobenz [de] oxazolo [5,4-g] -isoquinoline- 6-dione, namely: N-butyl-3-nitro-4 hydroxy-1 was obtained by the reaction of 4-bromo-1,8-naphthalene anhydride with imidization, nitration, hydrolysis and reduction , 8 naphthalimide, and then in the presence of boric acid, imine and benzoyl chloride reaction can be the target compound. In this paper, the spectral data of MS (Mass Spectrometry), nuclear magnetic resonance (NMR), infrared, ultraviolet and fluorescence are given.
