complexes were designed for the recognition of phosphorylated anions through coordination to the metal ion reinforced by hydrogen bonds involving the anion and NH groups of urea. The complexes were isolated and several adducts with pyrophosphate were characterized using X-raydiffraction measurements. Coordination of one of the urea nitrogen atoms to the metal ion promoted the hydrolysis of the ligands
我们报告了一系列具有不同配体的 Cu(II) 和 Zn(II) 配合物,这些配体含有用脲基团官能化的二吡啶基单元,可能含有或不含有苯基硼酸功能。这些复合物设计用于通过与由涉及尿素的阴离子和 NH 基团的氢键增强的金属离子配位来识别磷酸化阴离子。分离出复合物,并使用 X 射线衍射测量表征了几种具有焦磷酸盐的加合物。尿素氮原子之一与金属离子的配位促进了含有 1,3-二苯基脲单元的配体的水解,而带有 1-乙基-3-苯基脲基团的配体在室温下不会显着水解。分光光度法滴定结合 1H 和 31P NMR 研究,用于研究磷酸盐的结合,焦磷酸盐 (PPi) 和核苷 5'-多磷酸盐(AMP、ADP、ATP、CMP 和 UMP)。在水溶液(pH 7.0,0.1 M MOPS)中测定的缔合常数表明,与含有单个磷酸盐单元的阴离子相比,与 PPi、ADP 和 ATP 的结合更强。[CuL4]2+ 复合物对焦磷酸盐 (PPi)

3-oxazolidines. Reaction of cyanoacetamide with 3 in the presence of Na gave a tricyclic triaza(thia)indacene, derived from two molecules of 3. A reactionmechanism involving an initial attack of the anion 1- on the NCX (X = O, S) moiety gives an anion 18, which cyclizes intramolecularly and after tautomerization gives the mono-ring heterocycle. With the cyanoamides, the N- site of the ambident ion 18 attacks
