Abstract
Regioselective mono and dis-chloromethylation of cavitands have been prepar ed as an intermediate of a new cavitand derivative. Mono- and bis-aza-15-cr own-5 modified cavitands (4 and 5, respectively) have been obtained from mo no-and bis-chloromethylated cavitands, respectively. The metal binding prop erties of native cavitand (1), 4 and 5 were studied by H-1-NMR and UV-V is spectroscopy. (C) 1999 Elsevier Science Ltd. All rights reserved.
