Abstract :
Four isomers of methyl 2-deoxy-d-arabino-hexosides were isolated by HPLC as chromatographically homogeneous compounds. The rates of pyranoside isomerization (αp and βp) at 40 °C and of furanoside isomerization (αf and βf) at 26 °C were determined. A mechanism has been suggested for transformations taking place during isomerization of methyl 2-deoxy-d-arabino-hexosides in methanolic solution catalyzed with hydrogen chloride.
