    A method simply produces a narrowly distributed and high-purity polyalkylene glycol derivative having an amino group at an end without using a heavy metal catalyst. A method for producing a polyalkylene glycol derivative having an amino group at the end by reacting a compound represented by the general formula (V) with an alkylene oxide, then reacting a reaction product with an electrophile represented by the general formula (I), and deprotecting the obtained product without using a heavy metal: R A 3 O(R A 4 O) k-1 R A 4 O − M + (V) wherein R A 3 represents a linear; branched, or cyclic hydrocarbon group having 1 to 20 carbon atoms; R A 4 represents an alkylene group having 2 to 8 carbon atoms; k represents an integer of 2 to 5; and M represents an alkali metal; wherein R A 1a and R A 1b each independently represent a protective group of the amino group, or one of R A 1a and R A 1b represents H and the other represents a protective group of the amino group, or R A 1a and R A 1b bind to each other to form a cyclic protective group, and the protective group is deprotectable without using a heavy metal; R A 2 represents a linear, branched, or cyclic hydrocarbon group having 1 to 6 carbon atoms; and X represents a leaving group.
    一种方法通过将一个由一般式(V)表示的化合物与一种烷基氧化物反应,然后将反应产物与一个由一般式(I)表示的亲电试剂反应,并在不使用重金属的情况下去保护所得产物,从而简单地产生一个具有末端氨基的狭窄分布和高纯度的聚烷基二醇衍生物的方法:RA3O(RA4O)k-1RA4O−M+(V),其中RA3代表具有1到20个碳原子的线性、分支或环烃基;RA4代表具有2到8个碳原子的烷基基团;k代表2到5的整数;M代表碱金属;其中RA1a和RA1b分别独立地代表氨基的保护基,或者RA1a和RA1b中的一个代表H,另一个代表氨基的保护基,或者RA1a和RA1b结合在一起形成一个环状保护基,且该保护基可在不使用重金属的情况下去保护;RA2代表具有1到6个碳原子的线性、分支或环烃基;X代表一个离去基团。
