| Abstract: | 25,27-Dipropoxy-p-tert-butylcalix[4]crown-9 cone conformer 5 was readily synthesized via an intramolecular cyclization strategy in good yields.The structures of all the new compounds involved were confirmed by NMR,ESI-MS and elementalanalyses.All of them were proved to be in the cone conformation. |
| Keywords: | Calix[4]crown-9 Cone conformation Synthesis Intramolecular cyclization |
