摘要: The cuppedo- and cappedophanes described here are special cyclophanes whose structures mainly based on a m-terphenyl framework in which substituents cause the outer two rings to be roughly perpendicular central ring. With cuppedophanes, tethers link rings, one front of behind ring, form cup-shaped or concave molecule. Often some organic functionality is located within cup, attached C2, moiety. cappedophanes, an enclosed cavity formed by attaching cap via four tethers, each rings. Although there strong tendency self-filled rather than valuted latter can obtained provided that somewhat rigid 5′-position moiety carries bulky substituent. This methodology opens way for synthesis containing well-defined cavity. Synthetic routes these phanes discussed detail, as their NMR spectra, conformations, selective reactions.
