are typically required. Herein, we present mild, safe, and sustainable electrochemical strategies for the preparation of C19 steroids. A reagent and catalyst free protocol for the removal of the C17 side chain of corticosteroids via anodic oxidation has been developed, enabling several one‐pot, multistep procedures for the synthesis of androgen steroids. In addition, simultaneous anodic C17 side chain
许多有价值的C19雄激素的合成可以通过从更丰富的皮质类固醇中去除C17侧链,然后进一步衍生化所得的17-酮衍生物来完成。常规化学试剂对该合成策略造成重大缺陷,因为会产生大量废物,并且通常需要淬灭反应混合物和纯化17-酮类固醇中间体。本文中,我们提出了制备C19类固醇的温和,安全和可持续的电化学策略。已经开发了一种无需试剂和催化剂的方案,用于通过阳极氧化去除皮质类固醇的C17侧链,从而实现了几种一锅多步的合成雄激素类固醇的步骤。此外,
