isolation and characterization of 19-oxo Δ20,21 secodine (2) is described. This compound is the first example of a stabilized, potentially reactive secodine intermediate in alkaloid synthesis. It cyclized to minovincine (1) in 77% yield in refluxing m-xylene.
19氧代Δ的合成,分离和表征20,21 secodine(2)进行说明。该化合物是生物碱合成中稳定的,可能具有反应性的次生碱中间体的第一个实例。它环化,产率为77%minovincine(1)在回流的米二甲苯。
