Epimerisation-free Peptide Formation from Carboxylic Acid Anhydrides and Azido Derivatives

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

Asymmetric Induction during the Aminolysis of 5(4H)-Oxazolones from N-Benzoyl Amino Acids; Almost Specific Formation of One Epimer in the Reaction of the Oxazolone from N-Benzoyl-DL-t-leucine with Methyl L-Prolinate

Asymmetric induction during the aminolysis of 5(4H)-oxazolones from N-benzoyl amino acids was investigated using a series of amino acid esters as amine nucleophiles.The reaction of the oxazolone from N-benzoyl-DL-t-leucine with methyl L-prolinate was found to produce the diastereomeric D-L isomer, almost specifically, under appropriate conditions.

N-TERMINAL SUBSTITUENT AND SIDE-CHAIN INFLUENCES ON THE CHEMICAL SHIFTS OF PROTONS IN MODEL DIPEPTIDE SYSTEMS

(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

Studies on the Diastereoisomeric and Conformational Aspects of Benzoyl Dipeptide Esters, as a Means of assessing Racemisation using Nuclear Magnetic Resonance Spectroscopy

Distinct methyl ester signals in the 1H n.m.r. spectra of diastereoisomeric forms of benzoyl dipeptide methyl esters provide a means of estimating the isomer composition of diastereoisomeric mixtures.Analysis of the mixture derived from peptide-coupling r

Chiral Environments for Asymmetric Hydrogenation of Model Didehydro-Amino Acid Residues

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
