Acetyl galactopyranosides were obtained by the reaction of 3-acetyl tropolone and 3-acetamido-tropolone with acetyl-α-D-galactopyranosyl bromide,respectively, using AgCO₃ as catalyst. Because of the tautomerism of tropolone molecule there were two isomeric products corresponding to the two starting materials prepared by Koenigs-Knorr glycosidation. The structure of these products was confirmed by elemental analysis, IR and ¹H NMR spectra. The results confirmed the products obtained were acetyl galactopyranosides compounds containing tropolone moiety.
- tropolone,
- galactopyranoside,
- Koenigs-Knorr glycosidation
