Diindolylmethanes, III: IR- and NMR-spectroscopic investigations of arylsubstituted 2,2′-diindolylmethan-3,3′-bis[2-(acetylamino)propionicacid methylesters]

Abstract

Nα-Acetyltryptophanemethylester yields with aromatic aldehydes 2,2′-diindolylmethanes on hydrogen chloride catalysis. These compounds are stabilized in solution by intramolecular H-bonds. The racemic ester should form 32 stereoisomers. At roomtemperature there exist however four: one pair of enantiomers and two mesoforms. These results were supported by IR-,1H-and13C-NMR-spectrometric methods.
