  procedures are complementary but silver catalysts are more versatile and less sensitive to sterically congested starting materials. Chiral complexes formed by privileged phosphoramidites derived from chiral binol and optically pure Davies’ amines, and copper(II) triflate, silver(I) triflate or silver(I) benzoate are excellent catalysts for the general 1,3-dipolar cycloaddition between nitroalkenes and azomethine

  AgOAc/ThioClickFerrophos (TCF) complex catalyzed the 1,3-dipolar cycloaddition of azomethine ylides (glycine imino ester) to nitroalkenes. The corresponding endo-cycloadducts (88:12–98:2 endo/exo) were afforded in good yields with high enantioselectivities, up to 98% ee, without addition of external amine. AgOAc/TCF works as a bifunctional (Lewis acid and base) catalyst.

  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 α‐amino acid‐derived imino esters and nitroalkenes affording with high dr the exo‐cycloadducts 4,5‐trans‐2,5‐cis‐4‐nitroprolinates in high ee at room temperature. In general, better results are obtained using silver rather than copper(II) complexes. In many cases the exo‐cycloadducts can be obtained in enantiomerically pure form just after simple recrystallization. The mechanism and the justification of the experimentally observed stereodiscrimination of the process are supported by DFT calculations. These enantiomerically enriched exo‐nitroprolinates can be used as reagents for the synthesis of nitropiperidines, by ester reduction and ring expansion, which are inhibitors of farnesyltransferase.magnified image

  Chiral complexes formed by phosphoramidites such as (S-a,R,R)-9 and Cu(OTf)(2) are excellent catalysts for the general 1,3-dipolar cycloaddition between azomethine ylides and nitroalkenes affording the corresponding tetrasubstituted proline esters mainly as exo-cycloadducts in high er at room temperature. The exo-cycloadducts can be obtained in enantiomerically pure form just after simple recrystallization. DFT calculations support the stereochemical results.
