Jo. Durand et al., REDUCTIVE CYANATION - A KEY STEP FOR A SHORT SYNTHESIS OF (-)-(2S,3S)-3-HYDROXYPROLINE, Tetrahedron letters, 39(32), 1998, pp. 5743-5746
A short stereoselective synthesis of (-)-(2S,3S)-3-hydroxyproline has
been realized from L-malic acid as the source of chirality. The key st
ep was the reductive cyanation of the intermediate la, in high stereos
electivity and yield. (C) 1998 Published by Elsevier Science Ltd. All
