A convenient preparation of 2-substituted (S)-aziridines
摘要:
2-Monosubstituted (S)-aziridines (S)-3 were obtained by hydrogenation of (R)-2-sulfonyloxynitriles (R)-2 with LiAlH4 in good chemical yields and high enantiomeric excess.

Vicinal diols react with thionyl chloride to give 1,2-cyclic sulphites in quantitative yield, which undergo facile ring opening by lithium azide in dimethylformamide to yield azido alcohols and the latter in turn have been stereoselectively transformed into amino alcohols, aziridines and diamines.
