Synthesis of 2‐Benzyl‐3,4‐dihydronaphthalenes via Oxidative Radical Opening/Cyclization of Methylenecyclopropanes with Potassium Benzyltrifluoroborates
Here reports a copper-catalyzed approach for the synthesis of 2-benzyl-3,4-dihydronaphthalenes. The reaction was proposed to proceed by a sequence of radical addition, ring-opening, and cyclization of methylenecyclopropanes with potassium benzyltrifluoroborate. Such a method features operational simplicity, mild reaction conditions and widely functional group tolerance and accords a diverse array of
