P. Bravo et al., Stereoselective synthesis of enantiopure amino compounds, via Mitsunobu azidation of (2S,R-S)-1-(p-tolylsulfinyl)butan-2-ol, J CHEM R-S, (10), 1998, pp. 666-667
Azidation of (2S,R-S)-1-(p-tolysulfinyl)butan-2-ol under Mitsunobu conditio
ns is the key step for a highly stereoselective preparation of enantiomeric
ally pure amino compounds via chiral sulfoxide chemistry.
