Abstrakt: The first catalytic asymmetric [3 + 2] cycloadditions of Schiff bases of alpha-aminophosphonates with olefins have been developed. Chiral silver amide complexes bearing (R)-DTBM-SEGPHOS worked well as catalysts for the first time, and proline phosphonic analogues were obtained in high yields with excellent exo- and enantioselectivities.
