CAT3, one of the (+)-deoxytylophorinine-based phenanthroindolizidine alkaloids, is a promising therapeutic agent for the treatment of hedgehog (Hh)-driven glioblastoma and is currently being evaluated in preclinical studies. In this paper, a novel and practical synthetic route for CAT3 was firstly demonstrated with 10% overall yield in 11 steps and has been successfully validated for pilot-plant scale
CAT3是一种基于 (+)-deoxytylophorinine 的 phenanthroindolizidine 生物碱,是治疗刺猬 (Hh) 驱动的胶质母细胞瘤的有前途的治疗剂,目前正在临床前研究中进行评估。本文首次展示了一种新颖实用的CAT3合成路线,11 步总产率为 10%,并已成功验证用于中试规模制备。对菲3位取代的研究表明,给电子功能可以很好地保持S构型。特别是,通过引入强给电子叔叔实现了优异的CAT3对映体过量(≥99% ee )-丁基二甲基甲硅烷基 (TBS) 基团。
