    • A process for the preparation of N-substituted-hydroxycycloalkylamine derivatives, that are useful intermediates for the synthesis of various organic chemicals including pharmaceutical and agrochemical compounds, represented by formula (1), by reacting a 1,2-dihydroxalkyl alcohol, represented by the following formula (2), with a thionyl halide to produce an intermediate 1,2-cyclosulfinylalkyl halide represented by the following formula (3); and then cyclizing that intermediate with an amine compounds represented by the following formula (4). In the above structural formuli, * represents an asymmetric carbon atom; R1 is hydrogen or an amino-protecting group; m is an integer of 1-3; and X is halogen. The reactant compounds as well as the compounds made according to this invention have the following substitution pattern: n=1, R2=OH, R3=H and m=1; n=1, R2=H, R3=CH2OH and m=2; n=2, R2=OH, R3=H; and m=2; and n=2, R2=H, R3=CH2OH and m=3.
    • 一种制备N-取代羟基环烷基胺衍生物的方法,其为由式(1)表示的用于合成包括药物和农药化合物在内的各种有机化学品的有用的中间体,通过使由 (2)表示的亚硫酰卤,得到下式(3)表示的中间体1,2-环丙烷基烷基卤化物。 然后用下式(4)表示的胺化合物环化该中间体。在上述结构式中,*表示不对称碳原子; R1是氢或氨基保护基; m为1-3的整数; X为卤素。 反应物化合物以及根据本发明制备的化合物具有以下取代模式:n = 1,R 2 = OH,R 3 = H且m = 1; n = 1,R2 = H,R3 = CH2OH,m = 2; n = 2,R2 = OH,R3 = H; m = 2; n = 2,R2 = H,R3 = CH2OH,m = 3。
