Ring around the rosie: The effective enantioselective synthesis of the antimalarial nonenolide title compounds was achieved in a convergent strategy. Oxy‐Michael addition reaction was used to introduce the chiral methoxy group at C‐4, and ring‐closing metathesis (RCM) reaction (53 % yield) facilitated the key construction of the 10‐membered ring.
围绕玫瑰红:以收敛策略有效地合成了抗疟的壬烯内酯标题化合物。使用Oxy-Michael加成反应在C-4处引入手性甲氧基,开环复分解(RCM)反应(产率53%)促进了10元环的关键构建。
