A new series of chiral polyether-diester ligands has been prepared by reacting racemic and chiral diphenyl-substituted tetraethylene glycols with diglycolyl chloride (5 and 6), 2,5-furandicarbonyl chloride (7 and 8), 2,6-pyridinedicarbonyl chloride (9-12), and 4-methoxy-2,6-pyridinedicarbonyl chloride (13).The chiral diphenyl-substituted tetraethylene glycols were prepared from the dl-, (S)-, and (R)-mandelic acids.
