In the presence of a Cu(I)/NHC catalyst, the reactions of allylboronic pinacol esters with CO2 (1 atm) are highly regioselective, giving exclusively the more substituted β,γ-unsaturated carboxylic acids in most cases. A diverse array of substituted carboxylic acids can be prepared via this method, including compounds featuring all-carbon quaternary centers.
在Cu(I)/ NHC催化剂的存在下,烯丙基硼酸频哪醇酯与CO 2(1 atm)的反应具有很高的区域选择性,在大多数情况下,仅生成取代度更高的β,γ-不饱和羧酸。通过这种方法可以制备各种各样的取代羧酸,包括具有全碳季中心的化合物。
