Abstract
Cross-electrophile coupling reactions that forge C(sp3)-C(sp3) bonds are strategic methods for the synthesis of molecules with high F(sp3), yet very few employ electrochemical conditions as the necessary reductant. Herein, we report an electrochemical intramolecular cross-electrophile coupling reaction of 1,3-diol derivatives to access aliphatic and aryl cyclopropanes, including spirocyclic and fused bicyclic cyclopropanes. The scalable electrochemical cross-electrophile coupling (eXEC) reaction employs a nonsacrificial anode in an undivided cell.
