Nakano, Akio published the artcileCistulynes: proton NMR and single-crystal x-ray evidence for structure and cation encapsulation in a rigid, molecular channel model system, Recommanded Product: Propane-1,3-diamine dihydrochloride, the publication is Tetrahedron Letters (1989), 30(38), 5099-102, database is CAplus.
A novel, tetraacetylenic, macrotricyclic mol. receptor I, prepared by dimerization of N,N‘-dipropargyl-4,13-diaza-18-crown-6 with CuCl in the presence of Me2NCH2CH2NMe2, O, and Me2CHOH in 12% yield, is shown by x-ray crystallog. to have a channel-like structure and by NMR techniques to selectively accommodate both metallic and organic cations within its compartment.
