    摘要： The present invention is related to a method of producing a peptide, characterized in contacting a reaction mixture with a base after a condensation reaction to hydrolyze while a basic condition is maintained until a ratio of a remaining unreacted active ester of an acid component is decreased to 1% or less in a liquid phase peptide synthesis method. According to the invention, a target peptide of high purity can be simply and efficiently produced by a continuous liquid phase synthesis method. Further, the present invention is related to a method of producing a peptide, characterized in using an amide-type solvent immiscible with water in a liquid phase peptide synthesis method. According to the invention, various peptides can be produced by the liquid phase synthesis method without being restricted by the amino acid sequence of the target peptide.

    摘要： The objective of the present invention is to provide an optically active imidazolidinone derivative widely usable for synthesizing an optically active amino acid, a method of easily producing the derivative, and a method of easily producing an optically active amino acid by using the derivative. The objective can be achieved by producing an optically active amino acid using a novel optically active imidazolidinone derivative represented by a general formula (3) and the like. According to the method of the present invention, an optically active imidazolidinone derivative can be obtained by preferential crystallization from a mixture of isomers of the imidazolidinone derivative. Therefore, an optically active amino acid can be easily and stereoselectively produced without cumbersome procedures required for the conventional methods, such as resolution of diastereomers, synthesis from an optically active amino acid and resolution of isomers by silica gel column chromatography.

    摘要： The objective of the present invention is to produce an optically active 2-arylpiperazine derivative useful as a synthetic intermediate for pharmaceutical products and agricultural chemicals from inexpensive and readily available starting material by an industrially practicable method. The objective can be accomplished by treating an optically active substituted aminodiol derivative produced from an optically active styrene oxide derivative with a sulfonating agent in the presence of a base, and then reacting an amine compound to obtain the 2-arylpiperazine derivative. Especially, an optically active 1-unsubstituted-2-arylpiperazine derivative can be produced by treating an optically active 1-allyl-2-arylpiperazine derivative with water in the presence of a transition metal catalyst for deallylation.

    摘要： The present invention provides an industrially safe, easily operable process for producing an optically active epoxy alcohol derivative useful as an intermediate for pharmaceuticals from inexpensively available materials, and also provides a novel halohydrin derivative serving as an important intermediate for the epoxy alcohol derivative. Furthermore, the present invention provides a process for producing an intermediate for a triazole antifungal agent by allowing a halohydrin to react with a triazole sulfonamide, the process including a small number of steps. A process for producing an optically active epoxy alcohol derivative includes allowing an optically active α-substituted propionate derivative to react with a haloacetic acid derivative in the presence of a base to prepare an optically active haloketone derivative, allowing the resulting haloketone derivative to react with an aryl metal compound to stereoselectively prepare a halohydrin derivative, eliminating a substituent for the hydroxy group of the halohydrin derivative, and performing epoxidation with a base. Furthermore, a process for producing an intermediate for a triazole antifungal agent includes allowing a halohydrin derivative to react with a triazole sulfonamide, the process including a small number of steps.
