New β-formyl-2,5-dialkoxytetrahydrofurans were synthesized by hydroformylation of the corresponding 2,5-dihydrofurans. The aldehydes obtained react with 3-amino-1,2,4-triazole to give 6-(2-oxopropyl)-1,2,4-triazolo[1,5-a]pyrimidines.
通过相应的
2,5-二氢呋喃的加氢甲酰化合成了新的 β-甲酰基-2,5-二烷氧基
四氢呋喃。得到的醛与 3-
氨基-
1,2,4-三唑反应得到 6-(2-氧代丙基)-
1,2,4-三唑并[1,5-a]
嘧啶。
