Abstract: 1,2-Alternate p-tert-butylthiacalix[4]arene bearing at the lower rim 1,2-positioned acetamide fragments reacts with ethyl bromoacetate to give mono-O-alkylation product when Na₂CO₃ is used as a base and O,O′,N,N′-tetraalkylation one in the case of K₂CO₃.

Keywords: thiacalix[4]arene; synthesis; conformation; extraction.
