New type of amide conjugates of steroid and bile acids with D-glucosamine 1 and 2 were prepared. Title compounds are prepared via acid chloride or using N-[([(1E)-1-cyano-2-ethoxy-2-oxoethylidene]amino}oxy)(dimethylamino)methylidene]-N-methylmethanaminium tetrafluoroborate as condensation agent. They were examined for gelation properties with negative results. Per-O-acetylated D-glucosamine hydrochloride was prepared in one step procedure from D-glucosamine hydrochloride by acetylation in a mixture of acetyl chloride and acetic acid.
