✦ Synopsis
Regioselective mono and dis-chloromethylation of cavitands have been prepared as an intermediate of a new cavitand derivative.
Mono-and bis-aza-15crown-5 modified cavitands (4 and $, respectively) have been obtained from monoand bis-chloromethylated cavitands, respectively. The metal binding properties of native cavitand (1), 4 and $ were studied by ~H-NMR and UV-Vis spectroscopy.
