(Chemical Presented) 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).

The endo-diastereo- and enantioselective 1,3-dipolar cyclo-addition of azomethine ylides and electrophilic alkenes is ef-ficiently catalysed by chiral phosphoramidite-silver(I) Per-chlorate complexes. The reaction allows the presence of dif-ferent types o
