The reactivity of 1-(4-chlorophenyl)-3,5-diamino-1,2,4-triazole in multicomponent reactions with pyruvic acid and aldehydes and in two-component reactions with arylidenepyruvic acid was studied. The unusual direction of these treatments leading to the formation of unprecedented 3-[5-amino-1-(4-chlorophenyl)-1,2,4-triazol-3-ylamino]-5-arylfuran-2-ones instead of triazolopyrimidine or triazolylpyrrolone
研究了1-(4-氯苯基)-3,5-二氨基-1,2,4-三唑在丙酮酸和醛的多组分反应中以及在与亚芳基丙酮酸的二组分反应中的反应性。这些处理的不同寻常的方向导致形成了前所未有的3- [5-氨基-1-(4-氯苯基)-1,2,4-三唑-3-基氨基] -5-芳基呋喃-2-酮代替三唑并嘧啶发现或讨论了三唑基吡咯烷酮或三唑基吡咯烷酮衍生物。 杂环-多组分反应-呋喃-亲核试剂-区域选择性
