The transformation of easily accessible 2-vinylidenehydrofurans into stable 1,3-dienes has been achieved by using catalytic amounts of palladium(0). These valuable compounds were then engaged in subsequent Diels-Alder reactions giving access to complex heterocyclic cores found in numerous natural products. A rationale for the regioselectivity of the Diels-Alder reactions with vinylfurans has been provided
使用催化量的钯 (0) 已实现将容易获得的 2-亚乙烯基氢呋喃转化为稳定的 1,3-二烯。这些有价值的化合物随后参与了随后的 Diels-Alder 反应,从而获得了在众多天然产物中发现的复杂杂环核。DFT 计算提供了 Diels-Alder 反应与乙烯基呋喃的区域选择性的基本原理。
