摘要：
3-Heterocyclic coumarins were prepared in one-pot three-component reaction without catalyst. The mixture of salicylaldehydes, ethyl cyanoacetate, and o-aminophenols or o-phenylenediamines in refluxing n-butanol gave title compounds with good yields and high purity. Short reaction time, mild reaction condition, simple workup, and less waste are significant advantages of the presented method.
