摘要建立了3，3‘，4，4’-四-O-甲基鞣花酸的定量生产方法。以N-甲基-2-吡咯烷酮为溶剂，在氮气和空气中分别加入25%的二甲基硫酸盐和25%的甲氧基胍，对鞣花酸进行了甲基化反应。综述了由3，3‘，4，4’-四-O-甲基鞣花酸衍生的一系列聚合物前体的合成，包括未见报道的2，3，4，2′，3′，4′-hexamethoxy-6，6′-diphenoyl-dichloride，2，3，4，2′，3′，4′-hexamethoxy-6，6′-diisocyanato-diphenyl，2，3，4，2‘，3’，4‘-六甲氧基-6，6’-二氨基二苯基、2，3，4，2′，3′，4′-hexamethoxy-6，6′-dihydroxymethyl-diphenyl和2，3，4，2′，3′，4′-hexamethoxy-diphenyl-6，6′-dialdehyde.
Summary A quantitative method for the production of 3,3′,4,4′-tetra-O-methylellagic acid was developed. Ellagic acid was fully methylated under nitrogen and in air using dimethyl sulphate and 25% guanidinium methoxide in N-methyl-2-pyrrolidone. The synthesis of a range of polymer precursors derived from 3,3′,4,4′-tetra-O-methylellagic acid are outlined, including the previously unreported 2,3,4,2′,3′,4′-hexamethoxy-6,6′-diphenoyl-dichloride, 2,3,4,2′,3′,4′-hexamethoxy-6,6′-diisocyanato-diphenyl, 2,3,4, 2′,3′,4′-hexamethoxy-6,6′-diamino-diphenyl, 2,3,4,2′,3′,4′-hexamethoxy-6,6′-dihydroxymethyl-diphenyl and 2,3,4,2′,3′,4′-hexamethoxy-diphenyl-6,6′-dialdehyde.
