Boc-[20-C-6]-Bip-OMe 1, a new crown-carrier-α,α-disubstituted glycine with axial dissymmetry and a potential building block for the synthesis of polypeptide supramolecular devices, has been synthesized at the racemic state by phase transfer bis-alkylation of a glycine tert-butyl ester Schiff base with 2,2′-bis-(bromomethyl)-6,6′-dimethoxy-1,1′-diphenyl, followed by demethylation, esterification, N-protection and crown
