design and synthesis of a new type of ionophores with C2-symmetry is reported. The synthesis of seven different macrolides and a crown ether and their cation complexation properties were investigated. The X-ray crystal structure of some of the receptors provides valuable information on the preferred conformation of tetrahydropyrans in the solid state that can be related to the cation complexation properties
据报道,顺式-2-烷基-3-氧基-四氢吡喃单元是一种新型结构,用于设计和合成具有C 2对称性的新型离子载体。研究了七个不同的大环内酯和冠醚的合成及其阳离子络合性能。一些受体的X射线晶体结构提供了关于固态四氢吡喃的优选构象的有价值的信息,该构象可能与溶液中的阳离子络合特性有关。动力学模板效应已被证明是在大环氧化物3合成中提高产率和选择性的有用工具。
