Route design and proof of concept synthesis was conducted on a synthetically challenging atropisomeric KRASG12C inhibitor to support clinical API manufacture. Improvements to the synthesis of a chiral piperazine fragment gave reduced step count and streamlined protecting group strategy via the formation and methanol ring opening of an N-carboxy-anhydride (NCA). The complex atropisomeric nitroquinoline
在合成具有挑战性的阻转异构体 KRAS G12C抑制剂上进行路线设计和概念验证合成,以支持临床 API 制造。对手性哌嗪片段合成的改进通过N-羧基酸酐 (NCA)的形成和甲醇开环减少了步骤数并简化了保护基策略。复杂的阻转异构体硝基喹啉通过早期盐拆分获得,然后是正式的两部分硝基甲烷-羰基化,避免了之前导致阻转异构体消旋化的高温 Gould-Jacobs 环化。对于一系列邻位取代的溴/碘无保护苯胺,进一步探索了正式硝基甲烷-羰基化策略的底物范围。
