The synthesis of the prenylated indole alkaloids, malbrancheamide B and brevianamide B have been accomplished, starting with a prenylated proline derivative created using the Seebach ‘self-reproduction of chirality’ method, and using a cationic cascade sequence as the key step to form late-stage bridged diketopiperazine intermediates.
异戊二烯基吲哚生物碱,malbrancheamide B和brevianamide B的合成已经完成,首先是使用Seebach“手性的自我复制”方法创建的异戊二烯基脯氨酸衍生物,然后使用阳离子级联序列作为形成晚分子的关键步骤。桥联二酮哌嗪中间体。
