Herein, we propose a modular and general strategy to construct orcinol-type depsides based on the photolysis of functionalized benzodioxinones (I). Notably, resorcinylic esters are obtained without competing isocoumarin (II) formation, exemplified by the first total synthesis of gustastatin in 10 steps from commercially available trihydroxybenzoic acid.

在这里,我们提出了基于功能化的苯并二恶英酮(I)的光解反应来构建高脚酚型糊精的模块化和通用策略。值得注意的是,在没有竞争性异香豆素(II)形成的情况下获得间苯二酸酯,例如由市售的三羟基苯甲酸在十个步骤中第一次完全合成gustastatin。[结构:看文字]
