1-Amino-N,N-di­benzyl-1,6-di­deoxy-β-L-fructo­furan­ose

The title compound, C₂₀H₂₅NO₄, 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.

N-(p-Tol­yl)-β-L-rhamnopyran­osylamine 1.5-hydrate

The title rhamnopyran­osylamine, C₁₃H₁₉NO₄·1.5H₂O, 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, and these components are held together via extensive hydrogen-bonding inter­actions.
