A simple and efficientsynthesis of 4-aryl-4,5-dihydro-1H-indeno[1,2-b]pyridine derivatives has been achieved via a four-component cyclocondensation of 1,3-indanedione, aromatic aldehydes, β-ketoesters and ammonium acetate in one-pot in the absence of catalyst and solvent at room temperature on grinding. The present approach offers several advantages such as shorter reaction times, higher yields, low
通过1,3-茚满二酮,芳族醛,β-的四组分环缩合反应,可以实现4-芳基-4,5-二氢-1 H-茚并[1,2- b ]吡啶衍生物的简单有效合成在室温下,在不存在催化剂和溶剂的情况下,一锅法制得酮酯和乙酸铵。本方法具有几个优点,例如较短的反应时间,较高的产率,低成本,简单的后处理和容易的纯化。
