โฆ Synopsis
Reactions of tripodal amine I with tripodal esters 2 and 4, carried out in methanol under ambient conditions, afforded -as single products -tricyclic cryptands 3 and 5, respectively. Under the same conditions, the amine 1 reacted with dipodal esters 6 and 7 to give bis-macrocycles 9 and 10, respectively.
