A new method for α,α-diallylation of ketones catalyzed by palladium-phosphine complexes under neutral conditions has been developed. Allylation of β-keto carboxylates with allylic carbonates, followed by the decarboxylation-allylation as a one-pot reaction affords diallylated ketones in good yields.
开发了一种在中性条件下钯-膦配合物催化酮的α,α-二烯丙基化的新方法。β-酮基羧酸盐与烯丙基碳酸酯的烯丙基化,然后作为一锅法反应进行脱羧-烯丙基化,可得到高收率的二烯丙基化酮。
