Two novel chiral bipyrrolidine-derived phosphine ligands L1 and L2 were synthesized. The AgOTf + L1 protocol catalyzes the asymmetric [3+2] cycloaddition of azomethine ylides with alkenes to give highly substituted pyrrolidines in good yields (up to 90%) with moderate to high diastereoselectivities (up to >19:1 dr) and enantioselectivities (up to 76%).
