Rh(I)/Bisoxazolinephosphine-Catalyzed Regio- and Enantioselective Allylation of Indenes
A highly regio- and enantioselective synthesis of chiral 3-allyl-1H-indenes has been developed using a Rh(I)/bisoxazolinephosphine catalyst in combination with 4-dimethylaminopyridine (DMAP). The tridentate NPN* ligand binds tightly to Rh(I), effectively preventing catalyst deactivation by the indene products and ena...
