三异丙氧钐催化下β-酮酸烯丙酯的合成

Synthesis of Allylic β-Keto Esters Catalysed by Samarium Tri-2-propoxide

在甲苯中,以Sm(i-PrO)_3(10%)为催化剂,β-酮酸乙酯与烯丙醇进行酯交换反应得到中等产率的β-酮酸烯丙酯。

The transesterification of 3 - oxo esters with allylic alcohols in the presence of samarium tri - 2 - propoxide gives allylic [3 - keto esters in moderate yields.
