The reactions of nitrosyl chloride and dinitrogen tetroxide with acetylated glycals. Acetylated 2-deoxy-2-nitroso-α-D-hexopyranosyl chlorides and nitrates and acetylated 2-nitroglycals

Abstract: Reaction of nitrosyl chloride with acetylated glycals affords, with a high degree of stereospecificity, dimeric acetylated 1,2-cis-2-deoxy-2-nitroso-~-~-aldopyranosyl chlorides. Reaction of acetylated glycals with dinitrogen tetroxide, depending on the reaction conditions, can give either acetylated 2-deoxy-2-nitroso-a-D-aldopyranosyl nitrates as dimers or acetylated 2-nitroglycals. The mechanisms of these reactions are discussed.

“…The observed a-gluco configuration in 4 seems to offer further evidence for a four-center type addition mechanism as proposed by Lemieux and co-workers (10,11). Conversion of 4 into 2,3,4-tri-0-acetyl-6-0-ptolylsulfonyl-%-D-glucopyranosides was acconlplished by general procedures (6,7) and is illustrated in Scheme 1.'…”

“…[26,196] The focus of this section is on 2-nitroglycals, which have attracted much attention in the past decade. [34] Although 2-nitroglycals have been known for about 40 years, [197] their application in carbohydrate chemistry was limited until studies by Schmidt and co-workers in this field highlighted their potential. 2-Nitroglycals can be prepared readily from the corresponding glycals by the addition of acetyl nitrate generated in situ, followed by the basepromoted elimination of acetic acid.…”

“…196 Der Schwerpunkt dieses Abschnitts liegt auf 2‐Nitroglycalen, die jüngst viel Aufmerksamkeit erlangt haben 34. 2‐Nitroglycale sind seit etwa vierzig Jahren bekannt,197 aber ihre Anwendbarkeit in der Kohlenhydratchemie und insbesondere in der Glycosidsynthese wurde erst durch die Arbeiten von Schmidt und Mitarbeitern gezeigt. 2‐Nitroglycale können leicht aus den entsprechenden Glycalen durch Zugabe von in situ hergestelltem Acetylnitrat und anschließende basische Eliminierung von Essigsäure synthetisiert werden 198…”
