(R)-N-Methyl-N-diphenylphosphino-1-[(S)-2-diphenylphosphino)ferrocenyl]ethylamine is derived from (R)-(-)-N,N-Dimethyl-1-[(S)-2-(diphenylphosphino)ferrocenyl]ethylamine (D474193), which can be used as reactant/reagent in enantioselective palladium-catalyzed [3+2] cycloaddition of propargylic esters with β-ketoesters in presence of a chiral ferrocene/benzimidazole-based P,N-ligand.
