A series of cyclopenta[b]chromen‐1(9H)‐one derivatives is prepared in high yields by a one‐pot reaction of substituted salicylaldehydes and cyclopentane‐1,3‐dione in ionicliquids of [BMIm]Br, the procedure is very mild and environmentally benign.
通过取代水杨醛与环戊烷-1,3-二酮在[BMIm] Br离子液体中的一锅反应,可以高收率制备一系列环戊[ b ]铬n-1(9 H)-one衍生物,该方法非常温和,对环境无害。
