研究了一种简便的合成2位含氮杂环色酮类化合物的方法。1H-苯并三唑与ClCH~2COOH反应制得1H-苯并三唑-1-乙酸(1),以此为原料合成了一系列2位含1H-苯并三唑-1-甲基色酮(5)和相关的1,3,4-噁二唑衍生物(8)。

In this paper, a simple method for the synthesis of some chromones containing a nitrogen heterocycle substituted at 2-position is reported. 1H-Benzotriazolyl-1-acetic acid, readily obtained by reaction of 1H-benzotriazole with ClCH~2COOH, was used as starting material for synthesis of some chromones with 1H-benzotriazolyl-1- methyl at 2-position and related 1,3,4-oxadiazoline derivatives.

Key words: BENZOTRIAZOLE, CHROMONE P, BENZOTRIAZOLE, CHLOROACETIC ACID
