  • Title: Synthesis of large macrocyclic azacalix[n]pyridines (n = 6 - 9) and their complexation with fullerenes C(60) and C(70).
    Author: Zhang EX, Wang DX, Zheng QY, Wang MX.
    Journal: Org Lett; 2008 Jun 19; 10(12):2565-8. PubMed ID: 18484735.
    Abstract:
    Large methylazacalix[n]pyridines (n = 6-9) were synthesized effectively from the Pd-catalyzed macrocyclic fragment coupling reactions between alpha,omega-dibrominated and alpha,omega-diaminated linear oligomers. As macrocyclic host molecules, they formed a 1:1 complex with fullerenes C(60) and C(70) with association constants ranging from 3 x 10(4) to 1 x 10(5) M(-1).
