A process for the preparation of a 1,5-dideoxyazafuranose or 1,6-dideoxy-azapyranose is disclosed. In such a process, an azido-substituted .alpha.-ketose phosphate having a five- or a six-carbon chain is hydrogenated in the presence of a palladium catalyst. The carbon atom bearing the azido substituent and the carbon atom of the keto group of the .alpha.-ketose phosphate starting material are separated by two or three carbon atoms.
本发明公开了制备1,5-二去氧杂呋糖或1,6-二去氧杂
吡喃糖的方法。在这种方法中,一种带有五或六碳链的偶氮基取代的α-酮糖
磷酸酯在
钯催化剂存在下被氢化。α-酮糖
磷酸酯起始物的偶氮基取代的碳原子和酮基的碳原子之间相隔两个或三个碳原子。
