Catalytic Enantioselective 1,3‐Dipolar Cycloaddition Reactions of Azomethine Ylides and Alkenes by Using Phosphoramidite–Silver(I) Complexes

Abstract

Silver catalysts: A novel chiral phosphoramidite–silver perchlorate complex has been used for the synthesis of highly substituted pyrolidine rings. This method is valuable for the synthesis of biologically active α-substituted prolines by using hindered dipoles generated from α-substituted α amino acids (see scheme; DABCO=1,4-diazabicyclo[2.2.2]octane).
