✦ Synopsis

Abstract

Guest–host complex between cryptophane C, possessing two non‐equivalent caps, and chloroform is investigated by NMR spectroscopy. The kinetics of the chloroform exchange between the bound and free sites is determined by ^1^H exchange spectroscopy. Moreover, the preferential orientation of chloroform molecule with respect to the cryptophane C frame is examined by the NOESY and ROESY experiments. The experimental findings are compared to the results of quantum chemical calculations. Copyright © 2010 John Wiley & Sons, Ltd.

## Abstract The interaction between doxepin, a member of the tricyclic antidepressant (TCA) class of drugs, with β‐cyclodextrin (β‐CD) was investigated using NMR. Several TCAs have been reported to form a complex with β‐CD having 1:1 stoichiometry. Previous results from UV‐visible spectroscopy, flu

We present the synthesis of a series of deuterated cryptophanes 2 ± 6 by a slightly modified procedure used for cryptophane-A. We show that for [Xe@cryptophane] complexes the use of variable-temperature one-dimensional 129 Xe magnetization transfer (1D-EX-SY) allows the measurement of exchange rates
