The first synthesis of arabino-configured cyclic phosphonomethylphosphinates is described. The key step is the condensation of the triethylester of H-phosphinylphosphonate 10 on an hydroxyaldehyde 11 derived from a D-arabinal derivative followed by a cyclization induced under acetylation conditions.
R~:action of azido sugars with triphenylphosphine affords sugar phosphinimines [1,2], that are good precursors [3][4][5] for various nitrogen derivatives of sugars. In order to obtain aJ-amino sugar l'ormazan derivatives, the reduction of 6-azido-O-deoxy-o-galac-tosΒ’ N,N'-diphenylformazan [6] (1) wa
