New bisphosphine ligands for palladium-catalyzed desymmetrization of meso-cyclopent-2-en-1,4-diol biscarbamate

A new class of bisphosphine ligands (5, 6) with a cyclobutane backbone have been designed and synthesized on the basis of a privileged C2 scaffold of head-to-head coumarin dimer, among which ligand 5a was found to show excellent activity and en
