KH2 PO4催化Hantzsch反应合成4 H-色烯衍生物
Synthesis of 4 H-chromene Derivatives via Hantzsch Reaction Catalyzed by KH2PO4
摘要
Abstract
4H-chromene derivatives could be efficiently synthesized via Hantzsch reaction catalyzed by potassium dihydrogen phosphate , which is an inexpensive acidic inorganic salt .Under the optimized conditions , 4H-chromene derivatives could be directly separated in high yields via simple filtration .The filtrate containing potassium dihydrogen phosphate could be directly reused to catalyze this reaction for three times without appreciable loss of catalytic activity .It provided a practical and environmentally friendly method for the synthesis of 4H-chromene derivatives and had a good potential in industrial application .关键词
