A Conformationally Flexible Tetrahydroxycalix[4]arene Adopting the Unusual 1,3-Alternate Conformation

The use of a chiral solvating agent enabled the determination of the NMR-silent ring-inversion process of the ketocalixarene 3. Spectroscopic and crystal data indicate that 3 adopts the unusual 1,3-alternate conformation.
