标题 :Synthesis of cyclic peptides

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 programs. 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 preorganising 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.

摘要:The present invention provides a method for the continuous synthesis of a substituted benzoic-acid organic substance. The continuous synthesis method comprises: in the presence of catalyst and organic solvent, the organic matter represented by formula (I) and oxygen are continuously inputted to a continuous reaction apparatus for continuous oxidation reaction to obtain a substituted benzoic-acid organic substance, which is discharged continuously, the substituted benzoic-acid organic substance having the structure represented by formula (II). Oxygen is a green reagent and is inexpensive and readily available; a large amount of wastewater, waste gas, and solid waste is not generated after the reaction, and the system is easy to handle. The use of a continuous reaction operation can reduce the risk of flash distillation and explosion of solvent due to a high concentration of oxygen in a batch reaction. Under the same oxidation conditions, the continuous preparation process can reduce the escape of oxygen, greatly increasing the oxygen utilization rate and also simplifying the operation, improving the safety of the reaction and the yield of the substituted benzoic-acid organic substance.

标 题:Diversity-oriented synthesis of N,N,O-trisubstituted hydroxylamines from alcohols and amines by N—O bond formation
发明人：CRICH DAVID; HETTIKANKANAMALAGE ASIRI; HILL JARVIS
权利人:UNIV GEORGIA
摘要:In one aspect, the disclosure relates to a method for the direct synthesis of complex N,N,O-trisubstituted hydroxylamines by N—O bond formation. In another aspect, the method can successfully be employed using a wide variety of commercially available alcohols and secondary amines and enables the construction of large fragment-based libraries of trisubstituted hydroxylamines for drug discovery purposes. Also disclosed are N,N,O-trisubstituted hydroxylamines having low basicity, high stability at ambient temperatures, and an inherent lack of reactivity towards acetylating and sulfonylating enzymes that confer mutagenicity on less-substituted hydroxylamines.
