Copper-catalyzed Enantioselective Intramolecular Alkylboron Allylic Alkylation
A reductive C-C-bond-forming cyclization of vinyl-terminated allyl chlorides via alkene hydroboration with 9-BBN-H followed by Cu-catalyzed asymmetric intramolecular allylic alkylation with a new chiral phosphoramidite ligand produced six-membered ring compounds with a tertiary or quaternary stereogenic center in the ring with high enantioselectivity.
