摘要:
The reaction of N-tert-butylsulfinyl imines with nitromethane or nitroethane in the presence of NaHCO3 under solvent-free reaction conditions gave beta-nitro amine derivatives with reasonable levels of diastereoselectivity. Enantioenriched N-tert-butylsulfinyl protected a-amino acids or a-amino ketones are accessible upon oxidation of the adducts derived from nitromethane or nitroethane, respectively.
