title: A conformationally flexible tetrahydroxycalix[4]arene adopting the unusual 1,3-alternate conformation.
abstract: 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.
