4'──乙酰基缩氨脲基苯并15冠5的合成

THE SYNTHESIS OF 4' - ACETYLSEMICARBAZONYL B15C5

报道了在多聚磷酸（PPA）中将醚酰化的方法，合成了4'─乙酰基苯并15冠5，以此为原料，在酸性条仟下与氨基脲作用，合成了4'乙酰基缩氨脲基苯并15冠5．经由IR、MS和元素分析仪对合成的两种新物质的结构进行了鉴定．

4' - acetylB15C5 has been synthesized by crown ether acylation in polyphosphoric acid(PPA), it was then reactedwith semicarbazide under acid condition to give 4' - acetylsemicarbazonylB15C5. Two new prducts were characterized by elementalanalysis IR and spectrometry.
