A (3+2) cycloaddition between unbiased alkenes and 1,3-dicarbonyls is accomplished by judicious choice of electrode material and electrocatalyst to access dihydrofuran derivatives. A fluorinated porous carbon electrode with appropriate thickness governs unprecedented reactivity. This methodology eliminates the necessity for any stabilizing group within the alkene substrate. This is a rare example of the annulation of unbiased internal and terminal alkenes with cyclic and acyclic β-dicarbonyls.

无偏烯烃和 β-二羰基的电化学 (3+2) 环加成


通过明智地选择电极材料和电催化剂来实现无偏烯烃和 1,3-二羰基之间的 (3+2) 环加成，以获得二氢呋喃衍生物。具有适当厚度的氟化多孔碳电极控制着前所未有的反应性。该方法消除了烯烃底物内任何稳定基团的必要性。这是无偏内部和末端烯烃与环状和无环 β-二羰基成环的罕见例子。
