Kibdelones are hexacyclic tetrahydroxanthones and potent anticancer agents isolated from an Australian microbe. Herein, we describe the synthesis of a chiral, nonracemic iodocyclohexene carboxylate EF ring fragment of the kibdelones employing an intramolecular iodo halo-Michael aldol reaction and its merger with an ABCD ring fragment to afford the congener kibdelone C.
Kibdelones 是从澳大利亚微生物中分离出来的六环四氢氧杂蒽酮和强效抗癌剂。在此,我们描述了使用分子内碘卤-迈克尔醛醇反应合成 kibdelones 的手性、非外消旋碘环己烯羧酸酯 EF 环片段,并将其与 ABCD 环片段合并以提供同系物 kibdelone C。
