Abstract

Abstract 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- pyridinedicarbonyl 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 ( ...
