C. Agami et al., CYCLIZATION OF A CHIRAL OXAZOLIDINE AS A KEY-STEP FOR THE SYNTHESIS OF FUNCTIONALIZED PIPERIDINES, Tetrahedron letters, 37(23), 1996, pp. 4001-4002
Bicyclic oxazolidine 6, a potential precursor for the synthesis of ena
ntiopure piperidines and indolizidines, was synthesized from (R)-pheny
lglycinol. A stereoselective addition of cyanide anion on this compoun
d afforded ultimately (2S,3S)-3-hydroxypipecolic acid 9. (C) 1996 Publ
