✦ Synopsis

A variety of novel upper rim functionalized calix-[4]arenes have been synthesized, using the Tscherniac-Einhorn amidomethylation reaction. Partially or fully alkylated calix [4]arenes bearing propyl or ethoxyethyl substituents could be easily condensed with various N-methylol-amides and -imides under mild conditions. The resulting methyl-1

Synthetic routes were developed to link L-alanine methyl ester or L-alanyl-L-alanine methyl ester at the upper rim of calix [4]arenes blocked in the cone conformation. Several tetra-(3 and 6) and difunctionalized (11 and 12) amino acids containing macrocycles were obtained. Reaction of these compoun
