Synthesis of 1,2-bridged calix[4]arene-biscrowns in the 1,2-alternate conformation

[摘要] New methods to obtain 1,2-bridged calix[4]arene-biscrowns in the 1,2-alternate conformation are described. The stereochemistry of the proximal double functionalization reaction is mainly governed by the solvent, the length of the polyether units and the base used to deprotonate the calix[4]arene.
