Popis:	1.3-bisubstituted calix[4]crown 2 containing an ethylene was synthesized from p-t-butylcalix[4]arene 1 and 1, 2-dibromoethene in the presence of K2CO3. 2 was modified by 2+2' functional group disposition to produce the distal diether 3a in a 72% yield and selectively ipso-nitrated to give 3b in 61% yield.
