D-Altrose – general description and application

General description of D-Altrose:

Structure of D-Altrose

D-Altrose [1990-29-0] or (2S,3R,4R)-2,3,4,5,6-pentahydroxyhexanal is an aldohexose monosacharid, C-3 epimer of mannose. The pure compound is a colorless to offwhite crystalline solid with a melting point of 103-105 °C and a rotation at equilibrium [α] +32.6° in water.[1] It is an unnatural monosacharide that is soluble in water and almost insoluble in methanol.

D-Altrose can be prepared from levoglucosenone via D-altrosan, formed after stereoselective reduction and cis-hydroxylation.[2] D-altrose is formed as byproduct in the production of D-allose from D-psicose via epimerization catalysed with L-rhamnose isomerase.[3] Can be prepared from D-fructose using a combination of the immobilized D-tagatose 3-epimerase and D-arabinose isomerase but only with 6% overall yield.[4]

Application of D-Altrose:

D-altrose is used in synthesis of various unnatural analogues of biological active compounds like iminosugars.[5] Due to the lack of industrial production, application of D-altrose in different areas of research is still limited.
