Divergent access to E- or Z-trisubstituted medium-sized cycloalkenes by Pd-catalysed cycloaddition

Stereoselective access to either E- or Z-cyclic alkenes remains a formidable challenge. Now it has been shown that Pd-catalysed formal cycloaddition can lead to the construction of 11-membered heterocyclic alkenes. Ligand-induced divergent catalysis gives controlled access to either E- or Z-trisubstituted cycloalkenes starting from common terminal alkene substrates.
