This article may be used for non-commercial purposes in accordance with American Chemical Society Terms and Conditions for self-archivingWe report a highly enantioselective [3C + 2C] intramolecular cycloaddition of alkylidenecyclopropanes (ACPs) and alkenes. The best results are obtained by using sterically demanding chiral phosphoramidite ligands derived from Vapol. Moreover, we also show that related, but less bulky, phosphoramidites can also lead to very effective [4C + 3C] cycloadditions when dienes, instead of alkenes, are used as reacting partners. The reactions provide a practical, simple, and selective access to optically active, synthetically appealing 5,5- and 5,7-bicyclic systemseng© 2018 American Chemical SocietyAlkylidenecyclopropaneAsymmetricCycloadditionEnantioselectivePalladiumPhosphoramiditejournal article10.1021/acscatal.8b01296open access
