Some new hydrazone derivatives 3a–e have been obtained from 2-amino-3-formylchromone (1). Heterocyclization of thiocarbohydrazone derivative 3e via reaction with some electrophilic reagents afforded 1,2,4-triazoles 6–8 and 1,2,4-triazines 9–13. Condensation reactions of aldehyde 1 with o-aminoaldehydes and/or ketones afforded some new isolated and condensed heterocyclic systems 17, 19, and 20. The
一些新的腙衍生物 3a-e 已从 2-amino-3-formylchromone (1) 中获得。通过与一些亲电试剂反应,硫代碳腙衍生物 3e 的杂环化得到 1,2,4-三唑 6-8 和 1,2,4-三嗪 9-13。醛 1 与邻氨基醛和/或酮的缩合反应提供了一些新的分离和稠合杂环系统 17、19 和 20。筛选了新合成的化合物的抗菌活性。
