A series of mixed tetraethers of ealix [4]arene in which two distal substituents are methyl acetates and the other two are 1-aikenyl groups with 3-6 carbon atoms in the chain have been prepared by two mutes which differ in the order in which the group (methyl acetate or alkenyl) were introduced.

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.
