  摘要：

  (S)-2-Azidonitriles (S)-4 are easily accessible from (R)-2-(sulfonyloxy)nitriles (R)-2 by nucleophilic substitution with alkali azides 3 under complete inversion of configuration. The azidonitriles (S)-4 can be converted by catalytic hydrogenation into (S)-2-aminonitriles (S)-8 and by hydrogenation using LiAlH4 into (S)-1, 2-diaminoalkanes (S)-9, respectively, both, (S)-8 and (S)-9, isolated as hydrochlorides. Hydrolysis of the aminonitrile hydrochlorides (S)-8 HCl in a saturated solution of HC1 in alcohol gives (S)-2-amino carboxamide hydrochlorides(S)-10 . HCl with enantiomeric excesses >99% after recrystallization.
