A new synthetic method for the preparation of 2,6-disubstituted 4-aminopteridines is described. Treatment of 2-substituted 4,5,6-triaminopyrimidines with α-ketoaldoximes in MeOH affords in a regioselective one-step reaction 2,6-disubstituted 4-aminopteridines in high yield.
描述了一种制备2,6-二取代的4-氨基蝶啶的新的合成方法。在MeOH中用α-酮醛肟处理2-取代的4,5,6-三氨基嘧啶,可以进行区域选择性的一步反应,高产率地生成2,6-二取代的4-氨基哌啶。
