Cyclization under mild conditions of anthraniloyl‐ and N‐methyl‐anthraniloyl dipeptides*

Abstract
Anthraniloyl‐ and N‐methyl‐anthraniloyl dipeptides containing C‐terminal L and D proline residues have been synthesized and subjected to cyclization reaction under mild conditions. The influence of substituents and of the chirality of the residues on the output of the reaction is discussed.
