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.

Oxidative Cyclization of Amino Alcohols Catalyzed by a Cp*Ir Complex. Synthesis of Indoles, 1,2,3,4-Tetrahydroquinolines, and 2,3,4,5-Tetrahydro-1-benzazepine
oxidative cyclization of amino alcohols has been revealed. Indole derivatives are synthesized in good to excellent yields from2-aminophenethylalcohols by means of a [CpIrCl(2)](2)/K(2)CO(3) catalytic system. The present catalytic system is also effective for syntheses of 1,2,3,4-tetrahydroquinolines from 3-(2-aminophenyl)propanols and 2,3,4,5-tetrahydro-1-benzazepine from 4-(2-aminophenyl)butanol.
