Epimerisation-free Peptide Formation from Carboxylic Acid Anhydrides and Azido Derivatives
Bosch, Imma,Urpi, Felix,Vilarrasa, Jaume
, p. 91 - 92 (2007/10/02)
Conversion of C-terminal carboxy groups of N-protected α-amino acids to the corresponding 3,5-dinitrobenzoyl mixed anhydrides, followed by treatment with α-azido esters and trialkylphosphines, affords good yields of peptides, without appreciable formation
N-TERMINAL SUBSTITUENT AND SIDE-CHAIN INFLUENCES ON THE CHEMICAL SHIFTS OF PROTONS IN MODEL DIPEPTIDE SYSTEMS
Davies, John S.,Hakeem, Essam
, p. 1387 - 1392 (2007/10/02)
(1)H Chemical shift values of ester methyls in model dipeptide esters have been shown to be sensitive to (a) the nature and configuration of the constituent amino acids and (b) the spatial distance between the N-terminal aryl group and the ester protons.C
Chiral Environments for Asymmetric Hydrogenation of Model Didehydro-Amino Acid Residues
Davies, John S.,Eaton, Mark C.,Ibrahim, M. Nazar
, p. 1813 - 1814 (2007/10/02)
Nmr and glc analysis of diastereoisomeric mixtures of dipeptides has been used to study the asymmetric hydrogenation of model benzoyldidehydro- and trifluoroacetyldidehydro-dipeptide methyl esters.Chiral enhancement of one isomeric form appears to be inde
