A series of calix[10]crowns were synthesized for the first time. By reacting p‐tert ‐butylcalix[10]arene with ethylene glycol ditosylate or polyethylene glycol ditosylates in a system of K 2 CO 3 /toluene or Cs 2 CO 3 /acetone, a series of calix[10]crowns such as 1,2‐calix[10]crown‐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.
