2′-dihydroxybiphenyl. Sulfonation of the ligands led to water soluble agents. These ligands offer an alternative to synthetic hydroxamate or catecholate siderophores. The hexamethoxylated tripodal precursors and their completing ability towards alkali cations are also described. The complexing abilities of hexahydroxylated sequestering agents towards iron(III) are comparable to those of hydroxamate siderophores but
设计了一个新的铁螯合剂家族。具有六个会聚羟基的三脚架配体已经通过适当的邻,邻'-联芳基结构单元和间隔基的缩合制备。描述了为比较研究而设计的结构单元和简单的双齿配体的制备方法:几种方法已用于2,2'-二羟基联苯的邻官能化和3,3'-双官能化。配体的磺化导致水溶性试剂。这些配体提供了合成异羟肟酸酯或邻苯二酚铁载体的替代品。还描述了六甲氧基化的三脚架前体及其对碱金属阳离子的完整能力。
