  Synthetically useful N-Fmoc amino-alkyl isothiocyanates have been described, starting from protected amino acids. These compounds have been synthesized in excellent yields by thiocarbonylation of the monoprotected 1,2-diamines with CS2/TEA/p-TsCl, isolated as stable solids, and completely characterized. The procedure has been extended to the synthesis of amino alkyl isothiocyanates from Boc- and Z-protected amino acids as well. The utility of these isothiocyanates for peptidomimetics synthesis has been demonstrated by employing them in the preparation of a series of dithioureidopeptide esters. Boc-Gly-OH and Boc-Phe-OH derived isothiocyanates 9a and 9c have been obtained as single crystals and their structures solved through X-ray diffraction. They belong to the orthorhombic crystal system, and have a single molecule in the asymmetric unit (Z' = 1). 9a crystallizes in the centrosymmetric space group Pbca, while 9c crystallizes in the noncentrosymmetric space group P2(1)2(1)2(1).

  The synthesis of N,N′-disubstituted and N,N′,N′′-trisubstituted guanidine linked peptidomimetic molecules suitably decorated in the peptide backbone has been delineated. Nα-Protected amino acid derived S-methyl isothiouronium derivatives are employed as the key intermediates for the synthesis of guanidinopeptide mimics. Synthesis of a new class of carbodiimide tethered dipeptidomimetics has also been outlined wherein a Staudinger-aza-Wittig type reaction between amino alkyl azide and isothiocyanato esters is employed. Thus obtained carbodiimides have been demonstrated as starting materials for the construction of guanidino peptide mimics as well as an array of trisubstituted guanidine mimetics bearing N-hydroxy, cyano and amino function as third substitutions at the guanidino unit in the backbone.
