Abstract
Calix[4]arenes capped by diamide bridges in 1,3-position on the lower rim were synthesized. Regioselective alkylations of compounds 2 afford ed, 2, 4 O- and N-alkylated derivatives. Comprehensive NMR investigati ons were made to reveal the conformation of calix(aza)crowns 2, 3, 4. (C) 1997 Elsevier Science Ltd.
