摘要:
(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). © 2008 Wiley-VCH Verlag GmbH & Co.
