本文报道香料顺-3-己烯-1-醇(叶醇)(1)的新合成路线。1,1-二氯丁烯先后用三摩尔的正丁基锂处理后,中间体1-丁炔无需单离,再与环氧乙烷反应,可得3-己炔-1-醇(4)。在Lindlar催化剂存在下催化氢化4便得1。
This article reports the new synthetic route of the perfume cis-3-hexen-1-ol (phytol) (1). After 1,1-dichlorobutene is successively treated with three moles of n-butyllithium, the intermediate 1-butyne does not need to be isolated and reacted with ethylene oxide to give 3-hexyn-1-ol ). Catalytic hydrogenation of 4 in the presence of a Lindlar catalyst yields 1.
