摘 要:(±)-3-氨甲酰甲基-5-甲基己酸經(jīng)拆分得到(R)-(-)-3-氨甲酰甲基-5-甲基己酸,再經(jīng)Hofmann降解得到普瑞巴林。提供了(S)-(+)-3-氨甲酰甲基-5-甲基己酸的一種外消旋方法,外消旋體可以作為原料繼續套用,提高了原料利用率,降低了成本,有較高的應用價(jià)值,具有工業(yè)化應用前景。 |
關(guān)鍵詞:普瑞巴林;對映異構體;消旋;循環(huán)利用 |

Abstract:Pregabalin was obtained using(±)-3-carbamoylmethyl-5-methylhexanoic acid as the starting material by a two-step reaction including the racemic resolution and Hofmann degradation. A racemic method was also provided for(S)-(+)-3-carbamoylmethyl-5-methylhexanoic acid in this paper. The racemate could be reused as raw materials leading to lower raw material consumption, higher yield and lower cost for the production of Pregabalin. In addition, this novel method was environmentally friendly, suitable for industrial production with higher application value. |
Key words:Pregabalin; enantiomer; racemize; recycling |
