New method of synthesis of D-ribose and D-lyxose
Lacourt-Gadras,Grignon-Dubois,Rezzonico
, p. 281 - 288 (1992)
An attempt has been made to synthesize D-ribose from D-xylose using only commercial products and a minimum number of steps. D-xylose was transformed into pentenofuranoside which then was hydrolyzed. In the pyranose series, the unsaturated derivative could
