structures predominantly active in the central nervous system. The same results were obtained by coupling with N-Cbz-protected α-amino acids followed by microwave assisted hydrogenolysis. When the Fries rearrangement was carried out on the anilide derived from N-Boc−Ala−OH and the further coupling done with N-Cbz−(OMe)Asp−OH, the formed benzodiazepines could be inserted in a peptide chain for the preparation
