Abstract

Abstract This paper describes the development of novel aromatic platforms for supramolecular construction. By the Suzuki cross-coupling protocol, a variety of functionalized m-terphenyl derivatives were prepared (Schemes 1–4). Macrolactamization of bis (ammonium salt)(S, S)-6 with bis (acyl halide) 7 afforded the macrocyclic receptor (S, S)- 2 (Scheme 1), which was shown by 1 H-NMR titration studies to form 'nesting'complexes ...
