新鞣花酸衍生物的NMR归属

摘要

从鞣花酸(1)合成二个新的多取代的联苯化合物3和4,利用HMQC,HMBC和一维NOE谱技术确定了它们的13C和1H NMR归属.%Two polysubstituted biphenyl compounds were synthesized from ellagic acid.Using NMR techniques including HMQC,HMBC and 1D NOE techniques,the 13C and1H NMR chemical shifts of the two product compounds were assigned.
