Two calix[4] arene derivatives (5 and 8) and their telomers are synthesized to estimate selective extraction of alkali and transition metal cations from the aqueous to the organic phase (chloroform). Compound 5 shows selectivity toward Hg 2Ο© . Compound 8 and telomers 6 and 9 are not selective but a

β¦ Synopsis
Biologically active Vancomycin antibiotic mimics have been synthesized by linking two opposite aromatic nuclei of a calix[4]arene derivative in the cone conformation with a polifunctional bridge containing D-or L-alanine units and a diethylentriamine segment.
