各位大哥，谁知道这个物质怎么合成？谢谢！！！？ 六楼的大哥，以下是我所查到的摘要，里面提到了那个化合物是用哪些药品合成，但是却没有具体的合成路线以及实验条件，希望大家能帮帮小弟！万分感谢！ reaction of 2,3,3,-trimethyl-3h-indole with 1,3-dibromopropane. dopov. akad. nauk ukr. rsr, ser. b:geol. , khim. biol. nauki, 1979, (12), 1022-5(ukrain). reaction of 2,3,3,-trimethyl-3h-indole[1640-39-7] with 1,3-dibromopropane[109-64-8] or 1,3-propylene glycol di-p-toluenesulfonate[5469-66-9] gave 1,2,3,4-tetrahydro-10h-pyrido[1,2-a]indolium salts(i) rather than the expected bisquaternary compds. exhaustive dehydrogenation of i by s in dmf gave the corresponding 10,10-dimethyl-10h-pyrido[1,2-a]indolium salt. condensation of i with me2nc6h4cho, (eto)2choac, or 1,3,3-trmethyl-2-(formylmethylene)indoline, or with etoch:nph followed by condensation with various me-substituted quaternized heterocyclic amines gave a series of di- and trimethine dyes of general structureii (r=aryl, heterocyclyl, heterocyclylidenemethyl). the absorption max. of most of the dyes was shifted bathochromically in comparison. with those of corresponding cyanines in which the dimethyltetrahydropyridoindolinium nucleus was replaced by 1,3,3-trimethyl-indolium-2-ylmethylene. 查看更多
