(Z)-Axinohydantoin and (Z)-debromoaxinohydantoin, two pyrrole–imidazole alkaloids isolated from different marine sponges, possess moderate activities in inhibiting the progress of the cell cycle at different phases. A stereoselective synthesis of both natural products was achieved. The key step in the synthetic pathway was the installation of the hydantoin northern ring by using 1-benzoyl-2-methylsulfanyl-1
从不同海洋海绵中分离出的两种吡咯-咪唑生物碱(Z)-轴索乙内酰脲和(Z)-地溴代乙内酰脲,在不同阶段抑制细胞周期进程具有适度的活性。实现了两种天然产物的立体选择性合成。合成途径中的关键步骤是通过使用1-苯甲酰基-2-甲基硫烷基-1,5-二氢咪唑-4-酮来安装乙内酰脲北环。
