for the preparation of 4-R-furazan-3-carboxylic acid amidrazones (R = OMe, NH2, substituted amino group) by reductive opening of 1,2,4-oxadiazole ring in 4-R derivatives of (1,2,4-oxadiazol-3-yl)furazans by the action of hydrazine. The starting 1,2,4-oxadiazoles were synthesized from 4-aminofurazan-3-carboxylic acid amidoxime. Some chemical properties of the obtained compounds were studied.
已开发出另一种方法,可通过还原性打开4-R衍生物中的1,2,4-恶二唑环来制备4-R-呋喃赞-3-羧酸酰胺基R(R = OMe,NH 2,取代的氨基) (1,2,4-oxadiazol-3-yl)furazans通过肼的作用 起始的1,2,4-恶二唑是由4-氨基呋喃赞-3-羧酸a胺肟合成的。研究了所得化合物的一些化学性质。
