  Synthesis of ethyl 4-(1,2,3-thiadiazol-4-yl)-5-(bromomethyl)furan-2-carboxylate and its reactions with nucleophiles

  摘要：

  By cyclization of carboethoxyhydrazone of ethyl 4-acetyl-5-methylfuran-2-carboxylate under the conditions of Hurd-Mori reaction ethyl 4-(1,2,3-thiadiazol-4-yl)-5-methylfuran-2-carboxylate was synthesized. The ester obtained was brominated with N-bromosuccinimide at the methyl group in the furan ring. This bromide reacts with various N-, S-, O-, and P-nucleophiles to form the corresponding substitution products. Furylthiadiazole fragment remains stable in the course of these transformations.

  reactions of 5-methyl-4-(1,2,3-thiadiazol-4-yl)furan-2-carboxylic acid ethyl ester with some bases have been studied. The opening of 1,2,3-thiadiazole ring under the action of potassium tert-butylate in tetrahydrofuran in the presence of methyl iodide has led to the corresponding 4-methylsulfanylethynylfuran derivative. Under the action of potassium carbonate in DMF with an excess of primary amines or morpholine

  研究了5-甲基-4-（1,2,3-噻二唑-4-基）呋喃-2-甲酸乙酯与某些碱的反应。在存在碘甲烷的情况下，在四氢呋喃中叔丁醇钾盐的作用下，1,2,3-噻二唑环的打开导致产生了相应的4-甲基磺酰间乙炔基呋喃衍生物。在DMF中碳酸钾与过量的伯胺或吗啉的作用下，起始噻二唑形成了相应的呋喃乙酸硫代酰胺。5-甲基-4-（1,2,3-噻二唑-4-基）呋喃-2-甲酸乙酯与水合肼的反应导致酯基发生肼解反应而未裂解1,2,3-噻二唑环。
