摘要:苯肼与5-氯-2-戊酮经缩合、分子内成环及重排反应得到2-甲基色胺(2),继而和由(E)-4-甲基肉桂酸甲酯(3)与NBS溴化得到的(E)-4-溴甲基肉桂酸甲酯(4)发生N-烷基化反应制得(E)-3-[4-[[2-(2-甲基-1H-吲哚-3-基)乙胺基]甲基]苯基]丙烯酸甲酯盐酸盐(5)。5与过量的羟胺进行酰胺化反应制得抗肿瘤药帕比司他,总收率约40%(以3计)。
Phenylhydrazine reacted with 5-chloro-2-pentanone via a consecutive sequence of condensation, intramolecular cyclization and rearrangement to afford 2-methyltryptamine (2). Sequentially, 2 was alkylated with methyl (E) -4-bromomethylcinnamate (4), obtained from methyl (E) -4-methylcinnamate (3) by bromination with NBS, to give methyl (E) -3- [4- [ [2- (2-methyl- 1H-indol-3-yl) ethylaminol methyl] phenyl] acrylate hydrochloride (5). Compound 5 undertook amidation with excess hydroxylamine to achieve the target product panobinostat with an overall yield of about 40% (based on compound 3).
