As the key compound for the construction of cisoid terpenoids, (2Z ,6Z)-8-benzyloxy-1-chloro-2,6-dimethylocta-2,6-diene was synthesized stereoselectively via the Wittig reaction starting from nerol. The ten-carbon building block was coupled with prenyl or neryl p-tolyl sulfone to afford, after reductive desulfonylation, (Z,Z)-farnesol and (Z,Z,Z) -nerylnerol, respectively.
作为构建顺式萜类化合物的关键化合物,(2Z ,6Z)-8-苄氧基-1-氯-2,6-二甲基辛-2,6-二烯是以橙花醇为起点,通过威蒂什反应立体选择性合成的。该十碳结构单元与对甲苯砜的炔基或橙花酰基偶联,经还原脱磺后分别得到 (Z,Z)-farnesol 和 (Z,Z,Z) -nerylnerol。
