异羟肟酸 (HA) 可与多种金属离子形成稳定的络合物,从而提供具有高络合常数的异羟肟酸盐。异羟肟酸部分在天然铁代谢中起着至关重要的作用。在这项工作中,与羟基相连的 1,4,2-二恶唑作为关键化合物被引入,用于将异羟肟酸安装在合成聚合物的明确位置。开发了一种通用合成方案,该方案提供了一系列新的功能性关键构件,可普遍用于获得基于异羟肟酸的单体和聚合物,例如作为受保护的 HA 功能引发剂或用于合成各种新型基于 HA 的单体,例如环氧化物或甲基丙烯酸酯。为了证明二恶唑保护的异羟肟酸具有优异的稳定性,通过氧阴离子聚合。在温和的酸性条件下,方便的后续脱保护是可行的。α-功能性HA-聚醚,即聚乙二醇、聚丙二醇和基于环氧乙烷、环氧丙烷和乙氧基乙基缩水甘油醚的聚甘油,分别在1000-8500 g mol 分子量范围内具有低分散度(<1.2)-1。水溶性异羟肟酸功能聚(乙二醇)(HA-PEG)被探索用于各种生物医学应用和表面涂层。Fe(
Inspired by the unexpected reactivity of desulfated naturally occurring glucoraphenin, methods to synthesize thioimidate N-oxides (TIO) have been devised on simple or carbohydrate templates. Either through halocyclization or under Mitsunobu conditions, the starting thiohydroximates cyclized to generate efficiently the corresponding TIO.
Surface-modified zirconia nanoparticles and methods for making and using the same are provided. The surface-modifiers include non-metallic organic derivatives, comprising at least one hydroxamate functionality, wherein at least some of the non-metallic organic derivatives are attached to at least some of the zirconia nanoparticles.
