    摘要: A method for producing 4-borono-L-phenylalanine and its intermediates is provided.
    The method is for producing a compound represented by formula (II) from a compound represented by formula (I),


    wherein, in formulas (I) and (II),
    X represents Cl, F, Br, or I, R 1 represents NR 11 R 12 , R 11 represents H or a protective group of an amino group, R 12 represents a protective group of an amino group, R 2 represents COOR 21 , R 21 represents H or a linear or branched C1 to C10 alkyl group or benzyl group, R 3 represents H or COOR 31 , and R 31 represents a linear or branched C1-C10 alkyl group or a benzyl group; R 4 represents either boronic acid (B(OH) 2 ), boronic acid ester or boronic acid amide;
    Provided is a method of production comprising: a first step in which a compound represented by formula (I) reacts with a linear or branched C1-C10 alkylmagnesium halide in the presence of a metal halide; and a second step in which a boronic acid ester or boronic acid amide reacts with the compound obtained in said first step.
