Starting from tert-Butyloxycarbonyl(BOC)-Anthranilic-Acid(Abz) (1), BOC-Abz-Proline-Methyl-Ester (2) is synthesized. The crystal structure of both compounds are discussed. The conformational features of the crystal structures of 2 are compared with the conformation in solution. The whole conformational area (Φ and Ψ) of the amino acid part of 2 was investigated with the semi-empirical quantummechanical method AM 1, in order to check the general availability of the influence of ester functions to depsipeptide conformations. Cyclo-anthranoyl-prolinyl (3), which had already been described in the literature, forms crystals with a high density. Two independent molecules are found in the crystal structure; these molecules have very similar conformations.
