This study discloses an efficient synthetic route for the regiospecific construction of a C5 glycoside angucycline representative of mayamycin. The key steps are intramolecular aldol condensation and Hauser annulation, and the key precursor for the aldol reaction is accessible through utilization of α-lithiation of a vinyl ether.
这项研究公开了代表玛雅霉素的C5糖苷金环素的区域特异性构建的有效合成途径。关键步骤是分子内醇醛缩合和豪瑟环化,并且醇醛反应的关键前体可通过利用乙烯基醚的α-锂化来获得。
