α-环柠檬醛(2)为A环合成子,以间甲氧基苄基氯(3)为C环合成子,经缩合及分子内环化反应得关键中间体6.经1H NMR测试发现化合物6为全顺式结构.化合物6经氧化得双羰基化合物7.将7用t-BuOK/t-BuOH处理后得到烯醇式结构的化合物8.最后将异丙基通过Fridel-Crafts反应一步引入得到目标产物1.

By using α-cyclocitral (2) as the A ring synthon, and m-methoxy benzyl chloride (3) as the C ring synthon, the key intermediate 6 was obtained after the condensation and intracyclization reactions. Compound 6 was found to be an all-cis isomer through 1H NMR. The oxidation of 6 afforded the diketone 7, and the enolization of 7int-BuOK/t-BuOH afforded compound 8. Finally, the group of iso-propyl was introduced to compound 8 through Fridel-Crafts reaction to afford the target product 1.

Key words: 13-methoxy sempervirol-6-hydroxy-5,8,11,13-tetraen-7-one, total synthesis, tricyclic diterpene
