Deoxy sugars from aldonolactones

Deoxy-sugars can be synthesized from aldonolactones via -elimination or bromlnatlon procedures. 3-Deoxy-D-arablno-hexono-1,5-lactone, readily available from D-glucono-1,5-lactone by sequential acetylation, B-eliminatlon, hydrogenation, and deprotection, has been converted to 2-deoxy-D-erythro-pentose In 92)J yield by Indirect electrochemical oxidation. 3-Deoxy-D-arablno-hexose, which exists as a 53 30j 17 mixture o-f the o- and B-pyranose, and a-furanose forms In aqueous solution, has been synthesized by reduction of the 2,U,6-trl-0-benzoyl derivative of...
