The non-immune-suppressive cyclophilin inhibitor CRV431 is a clinical candidate to cure nonalcoholic steatohepatitis (NASH) and has the potential to treat liver fibrosis and cancer incidence. Herein we report a concise chemical semisynthesis of CRV431 in four steps from the commercially available cyclosporine, featuring in this the flow-chemistry-based methylenation an intermolecular ring-closing metathesis and a Rh-catalyzed diastereoselective hydrogenation.
非免疫抑制性环孢素抑制剂 CRV431 是一种治疗非酒精性脂肪性肝炎（NASH）的临床候选药物，具有治疗肝纤维化和癌症发病率的潜力。本文报道了从商业可得的环孢菌素经四步简洁化学半合成 CRV431 的方法，其特征在于基于流动化学的亚甲基化、分子间的环 closing metathesis 和 Rh 催化的非对映选择性氢化。
