A new systematic route to threefold protected natural polyamines, spermidine, spermine, thermine, and thermospermine, was developed through alternate regioselective manipulation on the terminal primary amino groups, starting from N,N-phthaloyl-1,3-propanediamine hydrochloride (3). When 3 was tosylated at the amine terminal and the phthaloyl terminal was subjected to transformation to the formamido
通过对末端伯氨基的交替区域选择性操作,从 N,N-邻苯二甲酰基-1,3-丙二胺盐酸盐 (3) 开始,开发了一种获得三重保护的天然多胺、亚精胺、精胺、热胺和热精胺的新系统途径。当3在胺末端甲苯磺酰化并且邻苯二甲酰基末端被转化为甲酰氨基,然后在甲苯磺酰基末端被例如N-(4-溴丁基)邻苯二甲酰亚胺取代时,以优异的产率获得了三重保护的亚精胺。甲酰胺基水解成胺盐后,一系列反应得到令人满意的重复,得到各种类型的三重保护的天然四胺。
