The first enantiospecific total synthesis of the alkaloids 16-epi-vellosimine (1), (+)-polyneuridine (2), (+)-polyneuridine aldehyde (3), and macusine A (4) is reported. The key oxidation was accomplished with the Corey-Kim reagent to provide the important biogenetic intermediates, 16-epi-vellosimine (1) and polyneuridine aldehyde (3), the latter of which is required for the conversion of the sarpagan
据报道,生物碱16-表-维罗西胺(1),(+)-聚神经氨酸(2),(+)-聚神经氨酸醛(3)和Macusine A(4)的第一个对映体全合成。关键的氧化反应是使用Corey-Kim试剂完成的,以提供重要的生物遗传中间体16-表-芹菜碱(1)和聚神经苷醛(3),后者需要将沙伯根骨架转化为阿杰玛兰系统。在Qubrachidine的生物合成中。[反应:请参见文字]。
