of the macrabicyclic ligands 1–11 containing pyridine, bipyridine, and biisoquinoline groups. They involve stepwise construction of the bicyclic system as will as direct macrobicyclisation procedures (Scheme 1) and give access to both symmetrical and dissymmetrical structures. Marked cation template effects have been found that facilitate the cyclisation processes. The ligands 1–11 were isolated as
已经开发了用于制备含有吡啶,联吡啶和双异喹啉基团的大环配体1-11的钠盐和锂盐酸盐的合成方法。它们涉及到双环系统的逐步构建,将其作为直接的大双环化程序(方案1),并且可以访问对称和不对称的结构。已经发现明显的阳离子模板效应促进了环化过程。分离出配体1-11,因为它们被Na +或Li +阳离子加密。
