摘要

A series of calix[10]crowns were synthesized for the first time. By reacting p-tert-butylcalix[10]arene with eth-ylene glycol ditosylate or polyethylene glycol ditosylates in a system of K2CO3/toluene or Cs2CO3/acetone, a series of calix[10]crowns such as 1,2-calix[10lcrown-4, 1,3-calix[10]crown-2, 1,2-calix[10]crown-3, 1,3-calix[10]crown-3,1,4-calix[10]crown-4 and 1,6-calix[10]crown-4 were obtained.
