标题 :Synthesis of 2-alkyl amino acids
发明人:CHORGHADE MUKUND S; GURJAR MUKUND K; MOHAPATRA DEBENDRA K
权利人:GENZYME CORP
摘要:Non-natural amino acids such as 2-alkylated amino acids allow for the synthesis of a wider variety of peptidal and non-peptidal pharmaceutically active agents. A method of preparing a 2-alkyl amino acid involves a Michael-type addition of a nucleophile to a dialkyl 2-methylidenylpropan-1,3-dioate and the conversion of a ester moiety into an amino moiety. The present invention also discloses a method of preparing a class of iron chelating agents related to desferrithiocin, all of which contain a thiazoline ring. In this method, an aryl nitrile or imidate is condensed with cysteine, a 2-alkyl cysteine, or a cysteine ester.

标 题:Synthesis of alpha fluoroalkyl amines
发明人:O'SHEA PAUL; GOSSELIN FRANCIS
权利人:MERCK FROSST CANADA LTD
摘要:This invention describes the reaction of an alpha fluoroalkyl ketone with a bis(trialkylsilyl)amide to give a stable N-trialkylsilyl imine. Treatment of the N-trialkylsilyl imine with an alcohol leads to solvolysis of the trialkylsilyl group and yields a stable mixture of an aminal and an imine in high yield. Catalytic reduction of this mixture, or of the individual components, in the presence of a chiral catalyst leads to a fluoroalkyl amine with high enantioselectivity and high yield.

权利人:JITSUBO CO LTD
摘要:The present invention has an object of shortening the process time and reducing use of a poor solvent for solidifying a carrier (Tag)-peptide component, by removing impurities without conducting solid-liquid separation (condensation, solid-liquid separation and drying operation) of a Tag-peptide component, in an Fmoc method using a Tag for liquid phase peptide synthesis. Provided is the peptide synthesis method that includes the following steps a-d: step a: a carrier-protected amino acid, carrier-protected peptide, or a carrier-protected amino acid amide, and an N-Fmoc-protected amino acid or an N-Fmoc-protected peptide are condensed in an organic solvent or a mixed solution of organic solvents, to obtain an N-Fmoc-carrier-protected peptide, step b: a water-soluble amine is added to the reaction solution after the condensation reaction, step c: the Fmoc group is deprotected from the protected amino group in the presence of a water-soluble amine, and step d: the reaction solution is neutralized by adding an acid, and further, by adding and washing with an acidic aqueous solution, then, by liquid-liquid separation an aqueous layer is removed to obtain an organic layer.
