Synthesis of (1R,2S)- and (1S,2S)-3-azido-1,2-dihydroxypropylphosphonates
Wroblewski, Andrzej E.,Glowacka, Iwona E.
, p. 989 - 994 (2002)
An efficient synthesis of diastereomerically pure dimethyl (1R,2S)- and (1S,2S)-3-azido-1,2-dihydroxypropylphosphonates from L-ascorbic acid, via new chirons: (2S,3S)-4-azido-3-benzyloxy-1,2-O-isopropylidene-1,2-butanediol and (2S)-3-azido-2-benzyloxypropanal was elaborated.
