Synthetic efforts toward poly(arylmethyl sulfone) dendrimers are described. A molecule designed to function as a protected AB 2 monomer, phenyl 3,5-bis(chloromethyl)benzenesulfonate was synthesized in four steps from dimethyl 5-sulfoisophthalate in 59% overall yield. This monomer was coupled to sodium benzenesulfinate to give the generation 1 monodendron, phenyl 3,5-his(phenylsulfonylmethyl)benzenesulfonate
描述了对聚(芳甲基砜)树枝状大分子的合成努力。设计用作受保护的 AB 2 单体的分子,3,5-双(氯甲基)苯磺酸苯酯是由 5-磺基间苯二甲酸二甲酯分四步合成的,总产率为 59%。将该单体与苯亚磺酸钠偶联,得到第 1 代单树枝,即 3,5-his(苯磺酰基甲基)苯磺酸苯酯。然而,通过文献中的还原和水解方法对第一代单枝树的去保护并不成功。
