A new member of the calix[4]crown family: Facile synthesis and characterization of a calix[4]crown-9 cone conformer
摘要:
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 elemental analyses. All of them were proved to be in the cone conformation.
