The first total synthesis of natural product ribisin A has been achieved in 11 steps from commercially available methyl α-d-glucopyranoside with 21.6% overall yield. The highly oxygenated benzofuran skeleton of this natural product was constructed, taking advantages of the inherent chirality of d-glucose, through the key reactions of Ferrier carbocyclization, Johnson iodination, Suzuki cross-coupling
从市售的甲基α-d-吡喃葡萄糖苷以11个步骤完成了天然产物核糖蛋白A的首次全合成,总收率为21.6%。通过Ferrier碳环化,Johnson碘化,Suzuki交叉偶联和Wacker氧化环化的关键反应,利用d-葡萄糖固有的手性构造了这种天然产物的高度氧化的苯并呋喃骨架。
