✦ Synopsis

Abstract

A series of new hetero‐macrocyclic diamide‐ester compounds (4a — 4z, 6a — 6b) were synthesized using 4‐(dimethylamino)pyridine as catalyst and characterization by infrared spectra, nuclear magnetic resonance spectra, mass spectra and elemental analyses. The structures of 4e and meso 4b were determined by X‐ray crystallography. The association constants of the compounds with various metal ions were determined by UV‐visible spectroscopic titration, and showed a selective recognition for certain metal ions.

tetrathiacyclooctadecane (3) have been obtained by intermolecular cyclization of 1,3-bis(2-bromoethyl)adamantane (4) with thioacetamide using a high-dilution technique. The reaction is concentration-dependent. The crystal structures of 1, 2, and 3 have been determined by single-crystal X-ray diffra
