Two steps are postulated in a new method of intramolecular peptide synthesis using oxalic acid derivatives (Fig. 1). Both are verified with model derivatives incorporating one sarcosine residue: cyclisation of 2d into 5 (Fig. 4) and aminolysis of 5 leading to 2h (Fig. 5). Glycine, alanine and phenyl- alanine derivatives however are not cyclizised in the studied conditions (attempted acid-, by trifluoroacetic
