| Abstract: | 3-(5’-Subsituted-benzooxazol-2’-yl)-7-diethylamino-chromen-2-ones were prepared by one-pot three-component reaction of 4-diethylaminosalicylaldehydes,ethyl cyanoacetate and o-aminophenols in refluxing n-butanol catalyzed by ZSM-5.This method has advantages of better yields and more environment-friendly process compared with that catalyzed by liquid catalysts. |
