highly convergent, stereoselective total synthesis of a ten-membered lactone, stagonolide G, is described. Epoxide ring-opening with vinyl Grignard, Yamaguchi esterification and ring-closing metathesis are the key steps involved in the present approach. d-Mannitol was used as a chiral pool material for the construction of both of the key fragments - the olefinic acid and the olefinic alcohol moieties. chiral
描述了十元内酯,stagonolide G的高度收敛,立体选择性的全合成。用乙烯基格氏试剂进行环氧化物开环,山口酯化和闭环易位是本方法涉及的关键步骤。d-甘露醇被用作手性池材料,用于构建两个关键片段-烯烃酸和烯烃醇部分。 手性池-格氏反应-酯化-闭环-大环
