  • Protected derivatives of tryptophan, processes for their preparation and their use for the preparation of dipeptide, polypeptide or protein structures
    Patent number: 5300651
    Abstract: A derivative of tryptophan is provided wherein the NH-group of the tryptophan indole nucleus is protected with tert.-butyloxycarbonyl (BOC) and the .alpha.-amino group is protected by 9-fluorenyl-methyloxy-carbonyl (FMOC). The carboxylic acid group of the tryptophan derivative may comprise a free COOH group, may be modified with a protecting or activating group, or may comprise an acyl group bonded to another chemical moiety, such as a polymer, another amino acid, a dipeptide, a polypeptide, or a protein. The tryptophan derivative is useful in the preparation of dipeptides, polypeptides or proteins containing at least one tryptophan-derived amino acid residue.
