    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： It is an objective to produce intermediates of optically active beta-3 adrenaline receptor agonists from readily available raw materials in a safe, efficient and industrially advantageous manner. A substituted acetylpyridine derivative represented by the general formula (9) is reduced by enantioselective reduction to produce an optically active hydroxyethylpyridine derivative represented by the general formula (10) (wherein * represents an asymmetric carbon atom), and it is further derivatized to an intermediate of an optically active beta-3 adrenaline receptor agonist, such as an optically active dihydroxyethylpyridine derivative represented by the general formula (14) or an optically active oxirane derivative represented by the general formula (16) .

    摘要： The present invention relates to a method for producing an optically active benzylamine derivative which is useful as an intermediate for pharmaceutical products and the like. In the present invention, an optically active benzylalcohol derivative is reacted with a sulfonylamide derivative in the presence of a phosphine derivative and an azodicarbonyl compound, to obtain an optically active benzylsulfonylamide derivative as a novel compound. Then, the thus-obtained optically active benzylsulfonylamide derivative is reacted with a thiol derivative, thereby producing an optically active benzylamine derivative. According to the present invention, the compound can be easily produced by a simple and short process without racemization.

    摘要： The present disclosure provides a reaction of a chlorine-containing compound using a flow reactor which is less restricted by a solvent to be used. In the present disclosure, an organic compound is produced by supplying a reaction substrate having at least one functional group which can react with chlorine and is selected from the group consisting of hydroxy group, a thiol group, an amino group, a carboxyl group, a thiocarboxyl group, and an acid amide group, and a chlorine-containing compound to a flow reactor together with a trialkyl amine having 9 to 40 carbon atoms and an organic solvent, and allowing the reaction substrate and the chlorine-containing compound to react with each other.
