Abstract
Copper(II) trifluoromethanesulfonate efficiently catalyzes the C-C coupling of 3-hydoxyisoindolinones with various aryl-, heteroaryl-, and alkenylboronic acids to furnish C(3)-substituted isoindolinones in 1,2-dicholoroethane (DCE) at reflux. The photolabile 2-nitrobenzyl protecting group is most appropriate for promotion of the coupling reaction and for deprotection.
