Oxidative [3+2] cycloaddition of 1,3-diketone and olefin using electroorganic chemistry

Electrochemically enabled (3+2) cycloaddition of unbiased alkenes and β-dicarbonyls

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.
