Abstract
Synthesis, separation and configurational analysis of phosphonated and partially phosphonated cavitands derived from resorcinarenes are desc ribed, The configuration of all diastereomers has been elucidated by t heir H-1, P-31 NMR spectra and C-13 relaxation times. In all cases the course of the bridging reaction favours the formation of the sterical ly more crowded stereoisomers having the P=O groups oriented outward w ith respect to the cavity.
