Abstract
A chiral 30-crown-10 derivative. DD-(2), has been prepared from 1,4:3,6-dianhydro-D-mannitol, D-(1), and shown by X-ray crystallography and dynamic 13C n.m.r. spectroscopy to adopt, in both the solid state and in solution, a ‘face-to-back’ conformation which must undergo substantial change in order to create the hydrophilic cavity necessary for the formation of complexes with Li+, Na+, K+, Rb+, NH4 +, MeNH3 +, and ButNH3 + ions.Keywords
