An inexpensive and eco-friendly Wittig olefination protocol has been developed to prepare novel (E)-5-styrylpyrimidines. The reaction of pyrimidine phosphonium ylide with different aryl/heteroaryl aldehydes underwent smoothly in the presence of sodium tripolyphosphate (STPP) in aqueous condition giving (E)-5-styrylpyrimidines (10a-t) in very high yields (77-96 %).
已开发出一种廉价且环保的 Wittig 烯化方案来制备新型 (E)-5-苯乙烯基嘧啶。嘧啶鏻叶立德与不同芳基/杂芳基醛的反应在三聚磷酸钠 (STPP) 存在下在水性条件下顺利进行,以非常高的产率 (77-96%) 得到 (E)-5-苯乙烯基嘧啶 (10a-t)。
