摘要：

The crystal and solution structures of diethoxycarbonylmethoxy-26,28-dimethoxy-t-butylcalix[4]arene (2) have been determined. This diester (2) adopts the less common partial cone conformation in the solid state, but in solution, 2 is fluxional at room temperature. Variable temperature H-1 NMR spectroscopy shows that at 250 K in CDCl3, 2 exists in a cone and a partial cone in a ratio of 43:57. (C) 2000 Elsevier Science Ltd. All rights reserved.
