摘要：

Hexahomooxacalix[3]arenes 1 bearing different substituents on their upper rim were synthesized from the corresponding Linear trimers 2 by the acid-catalyzed cyclization. The X-ray crystallographic analyses of 1 (R-1 = R-3 = H, R-2 = t-Bu, and R-1 = Et, R-2 = t-Bu, R-3 = i-Pr) revealed that they adopt a cone conformation, owing to an intramolecular hydrogen-bonded network in the solid state.
