A Silver-catalyzed enantioselective [3+2] cycloaddition of azomethine ylides with activated alkenes by using a P-stereogenic ligand Ganphos is reported. The method provides an efficient strategy for the effective synthesis of spirocyclic scaffolds containing a pyrroline motif. Notable features of this approach include good yields, remarkable enantioselectivity, as well as a broad substrate scope and significant step efficiency.

Key words: cycloaddition, silver catalysis, Ganphos, pyrroline
