The enantiospecific synthesis of the 14-membered diene unit of methyl sarcophytoate has been achieved by using the Sharpless asymmetric epoxidation, the aldol reaction, the oxy-Michael addition, and the modified Ito-Kodama cyclization as the key steps. All the carbon skeleton was derived from geraniol only.
已通过使用Sharpless不对称环氧化、醇醛反应、氧-Michael加成和改良的Ito-Kodama环化作为关键步骤,成功实现了甲基
