A series of substituted furo[3,2-e][1,2,4]triazolo[4,3-c]pyrimidines and furo[3,2-e]tetrazolo[1,5-c]pyrimidines were obtained from reactions of substituted 2-dimemylamino-4-hydrazmofuro[2,3-d]pyrimidines with orthoesters or sodium nitrite in acetic acid, respectively.
从反应中获得了一系列取代的呋喃并[3,2- e ] [1,2,4]三唑并[4,3- c ]嘧啶和呋喃并[3,2- e ]四唑并[1,5- c ]嘧啶分别用乙酸原酸酯或亚硝酸钠取代2-二甲氨基氨基-4-肼基氟呋喃[2,3- d ]嘧啶。
