Dirhodium tetrakis (S-(N-dodecylbenzenesulfonyl)prolinate (Rh-2(S-DOSP)(4)) catalyzed decomposition of methyl aryldiazoacetates in the presence of a substituted pyrrolidines results in highly diastereoselective and enantioselective C-H insertions, These reactions can proceed with impressive levels of double stereodifferentiation and kinetic resolution, which allows for three stereocenters to be controlled during the C-H insertion step.
