Enantioselective synthesis of axially chiral phthalides through cationic [Rh1(H8-binap)]-catalyzed cross alkyne cyclotrimerization

(Chemical equation presented). Easy access to axially chiral phthalides that bear one or two oxymethylene functionalities is provided by an enantioselective cross alkyne cyclotrimerization in the presence of the cationic complex [Rh1{(S)-H8-binap}]+. The axial chirality is introduced during the formation of the benzene ring with high enantioselectivity.
