Studies on the total synthesis of mumbaistatin, the -strongest natural inhibitor of G6P-T1, have culminated in the synthesis of a 4′′,8-dideoxy analogue. Key steps include a Diels-Alder reaction for the construction of the functionalized anthraquinone, a palladium-catalyzed Stille coupling to generate a tetra- ORTHO-sub-stituted diarylmethane, and a titanium-mediated alkynylation of an aldehyde to
对 G6P-T1 最强天然抑制剂孟买他汀的全合成研究最终合成了 4'',8-双脱氧类似物。关键步骤包括用于构建功能化蒽醌的 Diels-Alder 反应、钯催化的 Stille 偶联以生成四邻位取代的二芳基甲烷,以及钛介导的醛的炔基化以完成孟买他汀的碳骨架. 亚甲基桥的自由基溴化得到内酯,其类似于环化形式的目标结构。
