An enantiospecificsynthesis of a nuphar alkaloid was achieved in nine steps from N-Boc-(L)-proline. The alkaloid is a minor component of castoreum, which is secreted from the dried scent glands of a beaver. During the course of our study, the stereochemistry of three synthetic intermediates was verified by X-ray crystal structure analysis, which helped to resolve the existing discrepancies among reports
从 N-Boc-(L)-脯氨酸通过 9 个步骤实现了 nuphar 生物碱的对映特异性合成。生物碱是海狸香的次要成分,海狸香是从海狸干燥的气味腺中分泌出来的。在我们的研究过程中,通过 X 射线晶体结构分析验证了三种合成中间体的立体化学,这有助于解决有关该特定化合物结构的报告之间存在的差异。在我们合成的生物碱的基础上,我们提出了天然产物的结构。此外,对古希腊和罗马用于妇科目的的海狸香的治疗用途很感兴趣,我们进行了一项生物筛选,发现这种生物碱对催产素受体具有亲和力。
