Nội dung chính của bài viết
Tóm tắt
Ethyl 4-(4-nitrophenyl)-2,4-dioxobutanoate (1), ethyl 5-(4-nitrophenyl)isoxazole-3-carboxylate (2), 5-(4-nitrophenyl)isoxazole-3-carbohydrazide (3) and eight new N-substituted hydrazides (4a-h) containing isoxazole heterocycle were synthesized. The structures of these compounds were confirmed by IR and 1H-NMR spectral data.
