    摘要: A method of synthesizing nitrogen heterocycles such as indoles, indolines, oxindoles, quinolines, isoquinolines, and isoquinolones, all of which are pharmacologically active. The method involves cyclizing a haloaryl alkene in the presence of a catalytically effective amount of a palladium(II) ion source and in the presence of a cyclizing promoting base such as an alkali metal salt.

    摘要: The present invention relates to a method for manufacturing a boronic acid ester compound, characterized by reacting an aryl halide compound and a diboron ester compound in the presence of a nitrogen-containing organic base, a nickel catalyst, a phosphine compound and a solvent. According to the manufacturing method of the present invention, even if a nickel catalyst is used as the catalyst, a desired boronic acid ester compound can be obtained in a sufficiently high yield. Furthermore, even if aryl chloride or aryl bromide having relatively low price and low reactivity, was used as the aryl halide compound, a desired boronic acid ester compound can be obtained in a sufficiently high yield.
