摘要:
The precyclophane 1 derived from 2,6-bis(bromomethyl)pyridine and 2.1 equiv. of benzimidazole afforded pyridinobenz-imidazolophanes 6-8 on further reaction with I equiv. of 2,6-bis(bromomethyl)pyridine, 3,5 -bis(bromomethyl) ani sole and 1,3-bis(bromomethyl)-4-nitrophenol, respectively. A similar synthetic strategy was used for the synthesis of pyridinobenzotriazolophanes 9-11. Potential receptors 16 and 17 were also synthesized. (C) 2002 Elsevier Science Ltd. All rights reserved.
