The Kiliani reaction on 1-deoxy-(N,N-dimethylamino)-d-fructose, itself readily available from reaction of dimethylamine and d-glucose, proceeded to give access to the title β-sugar amino acid, C15H27NO7. X-ray crystallography determined the stereoch

The title compound, C 20H 25NO 4, the product formed in the Amadori rearrangement of L-rhamnose with dibenzylamine, is shown by X-ray crystallographic analysis to be a rare example of an Amadori product crystallizing in a furanose form. © 2005 Inter

The ring size of both the lactone and the ketal protecting group in the title compound, C9H14O5, have been established by X-ray crystallographic analysis. The crystal structure consists of hydrogen-bonded spirals parallel to the b axis.

The unknown relative configurations in the title compound, C13H13N3O4, of the acetal carbon and of the quaternary carbon bearing the azide were determined by X-ray crystallographic analysis; the absolute configuration was defined by the use of 2-C-me

Saccharinic acids, branched 2-C-methyl-aldonic acids, may be accessed via a green procedure from aldoses by sequential conversion to an Amadori ketose and treatment with calcium hydroxide; d-galactose and d-glucose are converted to 2-C-methyl-d-lyxon

The title tagatosamine, C20H25NO5.CH 4O, formed in the Amadori rearrangement of D-galactose with dibenzylamine, is shown to crystallize as the α-anomer, in contrast to the β-anomer formed in the Amadori reaction of D-glucose with dibenzylamine. ©

The title rhamnopyranosylamine, C 13H 19NO 4·1.5H 2O, was isolated as an intermediate in the Amadori rearrangement of L-rhamnose with p-toluidine. Two independent molecules and three water molecules of crystallization comprise the asymmetric unit, a
