Abstract3-Nitro-N-(phenylsulphonyloxy)phthalimide (IIIa) and N-(phenylsulphonyloxy)phthalimide (IIIb) were synthesised as key intermediates in good yield. Their structures were confirmed by 1H NMR and FTIR spectral data. The reaction of the key intermediates with allylamine produced 3-allyl-5-nitroquinazoline-2,4-(1H,3H)-dione (IVa) and 3-allylquinazoline-2,4-(1H,3H)-dione (IVb), respectively. Luminescence emission and excitation spectra of IVa and IVb are also presented.
摘要:3-硝基-N-(苯磺酰氧基)邻苯二酰亚胺(IIIa)和N-(苯磺酰氧基)邻苯二酰亚胺(IIIb)作为关键中间体被成功合成,产率较高。它们的结构经过1H NMR和FTIR光谱数据确认。关键中间体与烯丙胺反应分别产生3-烯丙基-5-硝基喹唑啉-2,4-(1H,3H)-二酮(IVa)和3-烯丙基喹唑啉-2,4-(1H,3H)-二酮(IVb)。同时还展示了IVa和IVb的发光发射和激发光谱。
