A　new　class　of　axially-unfixed　biaryl-based　pyrrolidines　with　C-2-symmetry　were　designed　and　synthesized　by　using　enantiopure　alpha-proline　as　a　chiral　source.　These　bifunctional　organocatalys　provided　Michael　adducts　in　high　chemical　yields　(up　to　99%)　and　with　excellent　stereoselectivities　(up　to　99:　1　dr　and　96%　ee)　in　the　direct　Michael　addition　reactions　of　a　variety　of　ketones　and　aldehydes　to　nitro　olefins.　The　transition　states　were　proposed　to　clarify　the　stereochemical　course　of　the　examined　reactions.
