Abstract : Dibenzobarallene ( 1 ) was utilized as the key intermediate for the syn-thesis of some new 2-substituted 1,4-dioxo-3,4,4a,5,10,10a-hexahydro-1 H - -5,10-[1’,2’]-benzenobenzo[ g ]phthalazine: 2 , 5a – d , 8a – c and 10 . Condensation of 2 with benzaldehyde or anisaldehyde gave the corresponding acrylonitrile derivatives 3a and , respectively. Thiophene derivatives b 4a and b were obtained
摘要:二苯并barallene(1)被用作合成一些新的2-取代的1,4-二氧代-3,4,4a,5,10,10a-hexahydro-1 H--5,10的关键中间体-[[1',2']-苯并苯并[g]酞嗪:2,5a – d,8a – c和10。2与苯甲醛或茴香醛缩合,分别得到相应的丙烯腈衍生物3a和3a。噻吩衍生物b 4a和b分别通过α与环己酮或环戊酮的Gewald反应获得。用乙酰氯或对甲苯磺酰氯处理5d,分别得到相应的酯6和7。用福尔马林环化8a – c得到相应的三嗪衍生物9a – c。用氢氧化钠将环10开环,得到相应的三唑衍生物11,当用戊基溴烷基化时,得到戊硫基衍生物12。建立了合成产物的代表性化合物,并将其评价为抗菌剂。关键字:二苯并barallene;酞嗪; 噻吩 三嗪 三唑 抗菌剂。介绍
