The synthesis of the oligo(catechol) systems 1-4 with different substituents, length of the connecting spacer, and number of catechol units is achieved by the use of various coupling reactions (e.g. Wurtz, Glaser-Eglinton, Stephens-Castro). In order to do this methods of preparing the building blocks, 2,3-dimethoxybenzyl bromides 5, 2,3-dimethoxyphenylacetylene (17), or 1,4-dibromo-2,3-dimethoxybenzene (23) have been developed starting with simple catechol (benzene-1,2-diol) derivatives.
不同取代基、连接间隔长度和儿茶酚单位数量的寡(儿茶酚)系统1-4的合成是通过使用各种偶联反应(如Wurtz反应、Glaser-Eglinton反应和Stephens-Castro反应)实现的。为了做到这一点,已经开发了制备构建块的方法,包括从简单的儿茶酚(苯-1,2-二醇)衍生物出发的2,3-二甲氧基苯基溴化物5、2,3-二甲氧基苯乙炔(17)或1,4-二溴-2,3-二甲氧基苯(23)。
