- Abstract
- Some galactose-oligopyridine conjugates were readily assembled by combining differently functionalized oligopyridines with
peracetylated galactose derivatives. Variation in the structure of the components and of the linkers employed for their connection afforded
adducts of different size, shape, and conformational mobility. Complexation of the bipyridine ligands with CuOTf and of the terpyridine
ligand with Zn(OTf)2 afforded the corresponding peracetylated 2:1 and 1:1 complexes, respectively, as single species. Their structures were
determined to be tetrahedral (Cu complexes) and trigonal-bipyramidal (Zn complex), on the basis of spectroscopic evidence. Removal of the
acetyl protecting groups from the ligands afforded the corresponding polyols. The terpyridine-Zn(II) complex, unlike the bipyridine-Cu(I)
complexes maintained their structures upon removal of the acetyl protecting groups. (literal)
