标题:Synthesis of organic polysulfide polymers
发明人：EFNER HOWARD F; SHAW JAMES E
权利人:PHILLIPS PETROLEUM CO
摘要:A process for preparing an organic polysulfide polymer, such as polyethylene trisulfide, is provided which comprises contacting a dimercaptan such as 1,2-ethanedithiol with elemental sulfur using a basic catalyst wherein the dimercaptan, elemental sulfur, and basic catalyst are each present in an effective amount to effect the preparation of the organic polysulfide polymer. A process for controlling the molecular weight of an organic polysulfide polymer is also provided which comprises contacting a mercaptan with a dimercaptan and sulfur, in the presence of a basic catalyst, under conditions sufficient to prepare an organic polysulfide polymer.

摘要:This invention relates to methods for preparing cyclic peptides and peptidomimetic compounds in solution and bound to solid supports, and to cyclic peptide or peptidomimetic libraries for use in drug screening programmes. In particular, the invention relates to a generic strategy for synthesis of cyclic peptides or peptidomimetics that enables the efficient synthesis under mild conditions of a wide variety of desired compounds. Two approaches were evaluated for their improvements in solution and solid phase synthesis of small cyclic peptides: positioning reversible N-amide substituents in the sequence; and applying native ligation chemistry in an intramolecular sense. Systematic investigation of the effects of preorganizing peptides prior to cyclisation by using peptide cyclisation auxiliaries, and developing new linkers and peptide cyclisation auxiliaries to aid cyclic peptide synthesis gives surprising improvements in both yields and purity of products compared to the prior art methods. The combination of these technologies provides a powerful generic approach for the solution and solid phase synthesis of small cyclic peptides. The ring contraction and N-amide substitution technology of the invention provide improved methods for the synthesis of cyclic peptides and peptidomimetics. When used in conjunction with linker strategies, this combination provides solid-phase avenues to cyclic peptides and peptidomimetics.
