Lower rim 1,3-disubstituted derivatives of calix[4]arene amides having amino acid ester and amines as pendants

Lower rim modification of calix[4]arene at its 1,3-alternate positions to r esult in the molecules of potential importance possessing amide bonds and o ther functional moieties as generated from the reaction between calix[4]are ne-1,3-diacid and the amino acids and/or substituted amines was carried out and the structural properties of the products were addressed.
