A general and efficient procedure for the stereoselective synthesis of (E)-(1-propenyl)phenyl esters from readily accessible allylphenols has been developed. The process involves a two-step sequence consisting of the initial acylation of the allylphenols with an acid chloride, followed by catalytic CC bond isomerization in the resulting allylphenyl esters. The latter step was performed in methanol
已经开发了从容易获得的烯丙基酚立体选择性合成(E)-(1-丙烯基)苯基酯的通用有效方法。该方法包括两步的步骤,该步骤包括烯丙基苯酚与酰氯的初始酰化,然后在所得的烯丙基苯基酯中进行催化的C C键异构化。使用可商购的双催化量(0.5摩尔%)(烯丙基) -钌(IV)二聚体[的RuCl(μ-Cl)的(η,在80℃下在甲醇中进行后者步骤3 η:3 -C 10 H 16 }} 2 ](C 10 H 16= 2,7-二甲基辛基-2,6-二烯-1,8-二基)。反应以高收率(68–93%)和短时间(4–9 h)进行,并具有完全的E选择性。
