新型树枝状分子3,5-二3,5-二(4-羧基苯甲氧基)苯甲氧基苯甲醇的合成

摘要

3,5-di(4-cyano benzyloxy) benzyl alcohol(4) and 3,5-di[3,5-di(4-cyano benzyloxy) benzyloxy] benzyl ￡ilcohol(6) were synthesized in turn by convergent growth method from 4-( bromom ethyl) benzonitrile and 3,5-dihydroxybenzyl alcohol. Two novel carboxyl-terminated dendrons, 3,5-di (4-carboxyl benzyloxy ) benzyl alcohol and 3,5-di[3,5-di(4-carboxyl benzyloxy ) benzyloxy ] benzyl al cohol , were prepared by the hydrolysis from 4 and 6, respectively. The structures were characterized by UV-Vis, 1H NMR, IR, MS and elemental analysis.%采用收敛法,以对氰基苄溴和3,5-二羟基苯甲醇为原料,依次合成了端基为腈基的芳醚树枝状分子3,5-二(4-腈基苯甲氧基)苯甲醇(4)和3,5-二[3,5-二(4-腈基苯甲氧基)苯甲氧基]苯甲醇(6)；4与6分别经水解制得以羧基为端基的新型芳基苄醚树枝状分子3,5-二(4-羧基苯甲氧基)苯甲醇和3,5-二[3,5-二(4-羧基苯甲氧基)苯甲氧基]苯甲醇,其结构经UV-Vis,1H NMR,IR,MS和元素分析表征.
