Mild rhodium(i) catalyzed ring opening of cyclopropane appended spirotricyclic olefins through C–H activation of arylboronic acids

Abstract

Herein we describe a ligand free rhodium(I) catalyzed stereoselective ring-opening of cyclopropane appended spirotricyclic olefins through C–H bond cleavage of boronic acid. The developed methodology leads to the formation of aromatic molecules functionalized with trans-disubstituted spiro[2.4]hept-4-ene and cyclopropane appended spirotricyclic framework via 1,4-alkyl to aryl rhodium migration.
