该中间体在本合成路线中的序号：(II)Synthesis of intermediate (VIII). The hydrochloration of 5-oxotricyclo[2.2.1.0~2,6~]heptane-3-carboxylic acid (II) gives 2-chloro-5-oxobicyclo[2.2.1]heptane-7-carboxylic acid (III), which is treated with peracetic acid yielding lactone (IV). This compound is treated with SOCl2 to obtain acyl chloride (V), which is converted into aldehyde (VI) by means H2 over Pd. The Horner-Emmons-Wiittig reaction of aldehyde (VI) and phosphonate (VII) by means NaH affords intermediate (VIII).
