Abstract
AbstractChiral complexes formed by privileged phosphoramidites and silver triflate or silver benzoate are excellent catalysts for the general 1,3‐dipolar cycloaddition between azomethine ylides generated from alpha‐amino acid‐derived imino esters and nitroalkenes affording the exo‐cycloadducts (4,5‐trans‐2,5‐cis‐4‐nitroprolinates) with high diastereo‐ and enantioselectivity at room temperature.
