A new chromatography-free synthetic route to triple reuptake inhibitor (1R,2S)-SIPI 5357 was developed and demonstrated on a 300-g scale. The key feature of this route is an asymmetric induction reaction, where the (2S,3S)-aminoketone 6 was highly stereoselectively reduced to (1R,2S,3S)-amino alcohol 7. After hydrogenation, chlorination, and cyclization, (1R,2S)-SIPI 5357 was prepared in 33% overall
开发了一种新的无色谱法合成三重吸收抑制剂(1 R,2 S)-SIPI 5357的合成路线,并在300 g规模上得到了证明。这条路线的关键特征是不对称诱导反应,其中(2小号,3小号)氨基酮6是高度立体选择性地还原成(1 - [R,2小号,3小号) -氨基醇7。氢化,氯化和环化后,通过7个步骤从α-溴代酮3制备(1 R,2 S)-SIPI 5357,总产率为33%。
