Tetrahydrocarbazole derivatives useful as androgen receptor modulators
chemoenzymatic asymmetricroute has been developed for the production of antimigraine agent (R)-Frovatriptan. Lipases and oxidoreductases have been identified as ideal biocatalysts for the production of enantiopure adequate synthetic intermediates under safe and environmentally friendly conditions. (S)-3-Hydroxy-2,3,4,9-tetrahydro-1H-carbazole-6-carbonitrile, an optimal building block for the synthesis
已经开发了一种简单的化学酶促不对称途径来生产抗偏头痛药 (R)-Frovatriptan。脂肪酶和氧化还原酶已被确定为在安全和环境友好的条件下生产对映体纯的合成中间体的理想生物催化剂。(S)-3-Hydroxy-2,3,4,9-tetrahydro-1H-carbazole-6-carbonitrile 是该药物合成的最佳结构单元,已通过 Candida antarctica 脂肪酶 B 型催化酰化其相应的外消旋混合物或醇脱氢酶A介导相应酮的生物还原。手性中心的反转已被确定为关键步骤,优化过程以避免部分外消旋化。最后,
