The total synthesis of kibdelone A has been accomplished via In(III)-catalyzed arylation of a heterocyclic quinone monoketal and iodine-mediated oxidative photochemical electrocyclization for construction of the ABCD ring moiety. Enzymatic dihydroxylation of methyl 2-halobenzoate substrates was employed for synthesis of activated 2-halo-cyclohexene F-ring fragments. A one pot oxa-Michael/Friedel-Crafts process allowed access to the first simplified DEF ring analogues of the kibdelones.
通过 In(III)催化的杂环醌单缩酮的芳基化反应和碘介导的氧化光电化学环化反应,实现了 kibdelone A 的全合成,构建了 ABCD 环部分。采用酶促二羟基化甲基 2-卤代苯甲酸酯底物合成了活化的 2-卤代环己烯 F 环片段。一锅法的氧杂-Michael/Friedel-Crafts 过程可以得到 kibdelones 的第一个简化的 DEF 环类似物。
