The reactions of acetylated α-D-glucopyranose with isocyanates gave the corresponding stereospecific 2-deoxy-D-glucopyranose. In this study a series ofacetylated α-glucosamine thiol ester were prepared using thiazolidine carboxylic acid, (ethylthio)acetic acid, (phenylthio)acetic acid, trifluoroacetic anhydride and phosphoric acid. The products were characterized using FT-IR and 1H NMR and solubility. The results showed that combining carboxylic acid with provides new products with improved physical properties. |
