Abstract: Aim to synthesize Nebivolol, as a new type of β-anderenergic blocker.We choose a rational synthesis route to prepare it.We choose two cheap compounds-Vitamin C and D-Mannitol as one source of chiral carbon.By the ring-closure reaction in the synthesis route, we introduce another two chiral points and get a mixture of two pseudosymmetric isomers.So we can get optical-pure intermediates by crystallization of the mixture and successfully resolve the problem of configuration.Finally, we complete the synthesis of Nebivolol by 10-step reaction.The overall yield is 12.7%.The synthetic method is also intensively studied and optimized in order to low-down the cost, simplify the operating procedure, and the yield gets better as well.

Key words: β-anderenergic blocker, Nebivolol, chiral intermediates, synthesis

摘要: 为了手性合成新型β受体阻断药Nebivolo,通过对文献路线的分析,基于经济高效的原则,选择了一条合理的合成路线,分别以廉价的维生素C和D-甘露醇作为手性源,通过环合反应的过程生成另一对手性碳。这样得到的非对映异构体,经过结晶得到光学纯的手性中间体,因而解决了结构中的构型问题。总共经过10步反应,成功地对Nebivolol进行了化学合成。改进后的新合成路线总收率12.7%,优化了合成路线,提高了收率,降低了成本,且节能环保。
