Nine pairs of cone and 1,3-alternate calix[4]arenes having distal propargyl or 2-azidoethyl groups at their phenolic oxygens were thoroughly studied at macrocyclization under copper(I) catalysis (CuAAC, copper(I)-catalyzed azide-alkyne cycloaddition). Though...

Cone and 1,3-alternate calix[4]arenes bearing pairs of 2-azidoethyl or propargyl groups, and 1,3-alternate calix[4]arenes having four 2-azidoethyl, four propargyl groups or pairs of 2-azidoethyl and silylated propargyl groups were explored...
