A 15-step chemoenzymatic total synthesis of C-1 methoxycarbonyl narciclasine (10) was accomplished. The synthesis began with the toluene dioxygenase-mediated dihydroxylation of ortho-dibromobenzene to provide the corresponding cis-dihydrodiol (12) as a single enantiomer. Further key steps included a nitroso Diels–Alder reaction and an intramolecular Heck cyclization. The C-1 homolog 10 was tested and
完成了C-1甲氧基羰基水仙环素( 10 )的15步化学酶全合成。合成开始于甲苯双加氧酶介导的邻二溴苯的二羟基化,以提供相应的顺式二氢二醇( 12 )作为单一对映体。进一步的关键步骤包括亚硝基狄尔斯-阿尔德反应和分子内赫克环化。测试并评估了C-1同源物10针对作为阳性对照的天然水仙环素( 1 )的抗增殖活性。报告了所有新化合物的实验和光谱数据。
