Abstract A convenient synthetic approach to polysubstituted dihydrogenated or heteroaromatic 1,2,4-triazolo[1,5-a]pyrimidines derivatives containing at position 5 a 4-methylpyrimidine moiety bearing a cycloamino substituent at position 2 and linked to the triazolopyrimidine bicycle through its position 5 was developed. The approach involves unusual three-component condensations of 3-amino-1,2,4-triazoles
摘要 一种方便的合成方法,用于多取代的二氢或杂芳族1,2,4-三唑并[1,5- a ]嘧啶衍生物,其在位置5处含有在位置2带有环氨基取代基的4-甲基嘧啶部分,并通过其位置与三唑并嘧啶自行车连接5被开发了。该方法涉及3-氨基-1,2,4-三唑,3-(2-R-4-甲基嘧啶-5-基)-3-氧代丙酸甲酯以及一系列C 1合成子的不寻常的三组分缩合。合成的等价物是从C 1合成子开始使用的一系列芳香族醛,原甲酸三乙酯或DMFDMA 。
