摘要：Potassium carbonate-catalyzed reactions of salicylic aldehydes with 3-methylpenta-3,4-dien-2-one, 3-benzylpenta-3,4-dien-2-one or ethyl 2-methylbuta-2.3-dienoate gave the corresponding functionalized 2H-1-chromenes in good to excellent yields and good stereoselectivities in some cases in DMSO at 120 degrees C within 1 h, respectively.
