  2,6-bis(bromomethyl)-4-tert-butylphenol 、 25,27-bis(4-(4-hydroxyphenyl)butoxy)-26,28-dihydroxy-p-tert-butylcalix<4>arene 在 zinc diacetate 作用下， 以 溶剂黄146 为溶剂， 以3.9%的产率得到16,33,39,45,50,60-hexatert-butyl-3,29-dioxaundecacyclo[29.15.7.710,22.18,12.114,18.120,24.137,41.148,52.02,43.030,35.158,62]hexahexaconta-1,8(65),9,11,14,16,18(64),20,22,24(56),30,32,34,37(55),38,40,43,45,48,50,52(54),58(66),59,61-tetracosaene-11,21,54,55,64,66-hexol

  摘要：

  New macrotricyclic compounds consisting of two calix[4]arene substructures connected by aliphatic chains of various length (three to five carbon atoms) between two opposite p-positions and two distal phenolic oxygens have been synthesized. Starting with p-tert-butyl-calix[4] arene, two O-protected phenolic units are attached via ether links in 1,3-position by reaction with the corresponding tosylates. After deprotection, the new calix[4]arene is formed by fragment condensation with 2,6-bisbromomethylated 4-alkylphenols. The structure of one example (8c) has been confirmed by single crystal X-ray analysis. Both calixarene parts assume the cone conformation, a molecule of acetonitrile being included in both cavities.
