A novel DABCO-catalyzed Ireland-Claisen [3,3]-rearrangement of allylic acrylates to give a-methylene-γ,δ -unsaturated carboxylic acids in the presence of an excess of TMSCl and DBU in refluxing acetonitrile was developed. The protocol provides an easy entry to a-methylene-γ,δ-unsaturated carboxylic acids from allylic alcohols in good yields.
在回流乙腈中存在过量 TMSCl 和 DBU 的情况下,开发了一种新型 DABCO 催化的爱尔兰-克莱森 [3,3]-烯丙基丙烯酸酯重排,以得到 a-亚甲基-γ,δ-不饱和羧酸。该协议以良好的收率提供了从烯丙醇中轻松进入 a-亚甲基-γ,δ-不饱和羧酸的途径。
