Abstract
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.
