Conversion of l-rhamnose into ten of the sixteen 1- and 6-deoxyketohexoses in water with three reagents: d-tagatose-3-epimerase equilibrates C3 epimers of deoxyketoses
摘要:
The efficient isomerization of L-rhamnose [the only cheaply available deoxy hexose] to 1-deoxy-L-psicose, 1-deoxy-D-psicose, 1-deoxy-L-fructose, 1-deoxy-D-fructose, 1-deoxy-L-tagatose, 6-deoxy-L-psicose, 6-deoxy-D-psicose, 6-deoxy-L-fructose, 6-deoxy-D-fructose, and 6-deoxy-L-tagatose is described. The conversion of rhamnose to ten of the sixteen 1- and 6-deoxyketohexoses is accomplished in water in three steps. The range of substrates for D-tagatose-3-epimerase (DTE) is extended to 1- and 6-deoxyketoses. An authentic sample of 6-deoxy-D-psicose is prepared from D-psicose. (C) 2009 Elsevier Ltd.

A polyol, found in the cell-wall of Nocardia asteroides R 399 as a component of a neutral polysaccharide mainly composed of D-arabinose and D-galactose, was identified by mass spectrometry, paper chromatography, thin-layer chromatography, and gas chromatography as 6-deoxy-D-altritol.
