Syntheses of the 4-nitrophenyl glycosides of hyalobiuronic acid and chondrosine.

Abstract

4-Nitrophenyl [sodium beta-D-glucopyranosyluronate]-(1-->3)-2-acetamido-2-deoxy-beta-D-glucopyranoside (1) and 4-nitrophenyl [sodium beta-D-glucopyranosyluronate]-(1-->3)-2-acetamido-2-deoxy-beta-D-galactopyranoside (2) were prepared from the zwitterions hyalobiuronic acid [beta-D-glucopyranuronic acid-(1-->3)-2-amino-2-deoxy-D-glucopyranose] and… (More)
