A new series of chiral macrocyclic polyether-diester ligands has been prepared from four chiral dimethyl substituted tetraethylene glycols (15a,b,16,17) and 2,6-pyridinecarbonyl chloride (products 5a-7), diglycolyl chloride (products (8-10), thiadiglycolyl chloride (product 11), 2,5-furandicarbonyl chloride (product 12), 4-chloro-2,6-pyridinedicarbonyl chloride (product 13), and 4-methoxy-2,6-pyridinedicarbonyl chloride (product 14).The chiral dimethyl substituted tetraethylene glycols (15a-17) were prepared from ethyl(S)-lactate.
