Efficient synthesis of alamethicin F-30 using a chloro imidazolidium coupling reagent, CIP

Alamethicin F-30 has been synthesized in solution using a CIP-additive as a coupling agent and TFA as a final deprotecting reagent. All couplings including those between sterically hindered α,α-dimethyl amino acid were successfully achieved by a 60 min re

RACEMIZATION AT PROLINE RESIDUES DURING PEPTIDE BOND FORMATION A STUDY OF DIASTEREOMERIC MIXTURES OF SYNTHETIC ALAMETHICIN FRAGMENTS BY 270 MHz 1H NMR

The stepwise synthesis of amino terminal pentapeptide of alamethicin, Z-Aib-Pro-Aib-Ala-Aib-OMe, by the dicyclohexylcarbodiimide mediated couplings leads to extensive racemization at the Ala and Pro residues.Racemization is largely suppressed by the use o
