o-Benzoquinone reacts with 3-substituted indoles under acidic conditions to give products having distinct UV characteristics. The o-benzoquinone derivation of N-acetyl-DL-tryptophan prepared in the presence of HCl was chromatography homogeneous and had 1 equiv of Cl- per molecular Potentiometric titrn. showed the presence of C:O and OH groups. Based on NMR, IR, and elementary analysis, structure I was assigned to the derivation in which the o-benzoquinone moiety is incorporated at the indole N atom of N-acetyl-DL-tryptophan.
