    • Surprisingly, C-glycosylnitromethanes are resistant to the Nef reaction commonly used for transformation of a nitro to a carbonyl group. A procedure for their simple conversion to C-glycosylcarboxylic (2,6-anhydroaldonic) acids has been announced: Köll P.; Dromowicz, H. Abstr. Eur. Carbohydr. Symp., 6th, Edinburgh, 1991, B56.

    • Ozonolysis of sodium nitronate forms of sugar nitro derivatives, some of which also contain the acetamido functionality, to carbonyl derivatives has been previously described, (a) Lattová, E.; Petrušová, M.; Petruǎ, L. Chem. Pap. 1991, 45, 823-827.

    • Ozonolysis of silyl nitronates of C-glycosylnitromethanes, not containing an acetamido functionality, to C-glycosylformaldehydes has also been described: Martin, O. R.; Khamis, F. E.; Rao, S. P. Tetrahedron Lett. 1989, 30, 6143-6146.

    • Optimized excess for the conditions used. An excess of NaOH was necessary to assure complete disappearance of starting 2 (cf. note 12), as a part of 3 formed was subsequently oxidized to acid 4, which consumed the extra base.

    • 3 (a side product of the ozonolysis of sodium nitronates) and acid 4. If 2 was not completely reacted in the ozonolysis step, it contaminated intermediate 5 and the other products, from which it was difficult to separate by both recrystallization and column chromatography.

    • 4 used as catalyst had to be added to the ice-water mixture; otherwise only underacetylated species were isolated.

    • note
    • A series of model compounds with the acetamido functionality was prepared to support the interpretation (to be published separately). It was indicated that a strain influencing the acetyl group to be eliminated had to be present. In this case, a parallel interaction with an unbonded electron pair of the ring oxygen atom seemed to provide the necessary strain.
