A　series　of　novel　axially　chiral　2,2-bipyridine　N,N-dioxides　bearing　C1　or　C2-symmetry　have　been　synthesized　by　the　use　of　enantiopure　-amino　acids　as　chiral　sources.　The　absolute　stereochemistry　of　the　axial　chirality　of　these　organocatalysts　has　been　clearly　assigned　by　means　of　CD　measurements　together　with　literature　protocols.　The　reactivities　and　enantioselectivities　of　these　organocatalysts　have　been　examined　in　the　reactions　of　aromatic　aldehydes　with　allyltrichlorosilane,　thus　providing　the　desired　products　with　moderate　yields　and　enantioselectivies.
