We report the first asymmetric synthesis of amidinomycin, an antiviral antibiotic metabolite. Amidinomycin of high enantiomeric purity (ee 91%) was prepared from norbornylene in 8 steps. The key step is an enzymatic discrimination of enantiotopic groups in meso cis-1,3-dicarbomethoxycyclopentane or in meso cis-cyclopentane-1,3- dicarboxylic acid anhydride.
我们报告了抗病毒抗生素代谢物氨基脲霉素的首次不对称合成。高对映纯度(ee 91%)的氨基脲霉素是通过8步从诺博尔烯制备而成。关键步骤是对meso cis-1,3-二甲氧基环戊烷或meso cis-环戊烯-1,3-二羧酸酐中的对映体组进行酶促选择。
