A stereoselective route to enantiomerically and diastereomerically pure pentasubstituted pyrrolidines has been developed by using reductive deoxygenation of quaternary α-hydroxy N-Boc pyrrolidine derivatives prepared from alkylation of the functionalized homochiral lactams. Stereochemistry of the new stereogenic center generated has been comfirmed unambiguously to be R by the formation of C2-symmetrical
