Résumé
Procedures were developed for the prepn. of Na and Li cryptates of macrobicyclic ligands contg. pyridine, bipyridine, and biisoquinoline groups. They involve stepwise construction of the bicyclic system as well as direct macrobicyclization procedures and give access to both sym. and dissym. structures. Marked cation template effects facilitate the cyclization processes. The ligands were isolated as their cryptates with Na+ or Li+ cations. [on SciFinder(R)]
