anion [MCl4]2– (where M = Cu, Co, Cd, Zn, and Hg) as the primary coordination sphere to synthesize new second sphere adducts. By introducing an alkyl spacer−(CH2)n– (n = 1, 2, 3, 4) to bibenzylamine (L0), the ligands L1, L2, L3, and L4 with higher degree of flexibility were synthesized. Different guest molecules such as alcohol, acetic acid, acrylic ester, or acetonitrile can be included in the host framework

The development of new chemical entities against the major diseases caused by parasites is highly desired. A library of thirty diamines analogs following a minimalist approach and supported by chemoinformatics tools have been prepared and evaluated against apicomplexan parasites. Different member of the series of N,N′-disubstituted aliphatic diamines shown in vitroactivities at submicromolar concentrations
迫切需要开发新的化学实体来对抗寄生虫引起的主要疾病。遵循极简主义方法并在化学信息学工具的支持下,已经制备了 30 个二胺类似物的文库,并针对 apicomplexan 寄生虫进行了评估。 N , N'-二取代脂肪族二胺系列的不同成员在亚微摩尔浓度下表现出体外活性,并且对弓形虫以及对氯喹敏感和耐药的恶性疟原虫菌株具有高选择性。为了证明仲胺的重要性,合成了十种N , N , N ', N'-四取代的脂肪族二胺衍生物,其活性比它们的二取代对应物低得多。进行理论研究以确定控制化合物活性的电子因素。

Synthesis of Chelating Complexes through Solid-State Dehydrochlorination Reactions via Second-Sphere-Coordination Interaction with Metal Chlorides: A Combined Experimental–Molecular Modeling Study
solid-state reactivity showed that the chelating complexes resulting from the mechanochemical dehydrohalogenation reaction depend on the formation of quasi-chelating hydrogen-bonding salts. Quantum-mechanical calculations have been used to gain insight in this mechanochemical dehydrohalogenation reaction, demonstrating that not only is size matching between reactants is important but also conformational energies
3-diamine) (L2), with (CH2)3 alkyl chains attached to the two N atoms. The ligands are double protonated and can react with tetrachloride metal dianion [XCl4]2– (X = Zn, Hg) in the presence of methanol solvent, leading to a series of new inclusion complexes, (CH3OH)2 ⊂ [L1]2H+· [ZnCl4]2–(crystal 1), (CH3OH)0.5 ⊂ [L2]2H+·[HgCl4]2 (crystal 2), and CH3OH ⊂ [L2]2H+}0.5· [ZnCl4]2–}0.5 (crystal 3).
