An efficient three-component protocol is described for the synthesis of benzo[6,7]cyclohepta[1,2-b]pyridine derivatives using β-chloroacroleins, 1,3-dicarbonyls and ammonium acetate under catalyst free conditions by using ethanol as reaction media. The mild reaction conditions, operational simplicity and high yields are the advantages of this protocol and the broad scope of this one-pot reaction makes
描述了一种有效的三组分方案,该方案用于在无催化剂条件下使用乙醇作为反应,使用β-氯丙烯醛,1,3-二羰基和乙酸铵合成苯并[6,7]环庚[1,2- b ]吡啶衍生物媒体。温和的反应条件,操作简便和高收率是该方案的优点,并且这种一锅法反应的广泛范围使该方法在实际应用中很有希望。筛选所有最终化合物的抗炎活性。在测试的化合物中,化合物5a,5b,5c,5d,5f和5k 表现出对IL-1β和MCP-1分泌的显着抑制,以此作为抗炎活性的指标。
