The synthesis of various optically active α-trifluoromethylamines has been realized from β-amino-α-trifluoromethyl alcohols via an aziridinium ion intermediate under kinetic conditions.
Diastereoselective synthesis of β-amino-α-(trifluoromethyl) alcohols from homochiral α-dibenzylamino aldehydes

Homochiral α-dibenzylamino aldehydes, prepared from the corresponding α-amino acids, react with trimethyl(trifluoromethyl)silane in THF at 0 °C to afford, in good yields and dr, β-amino-α-(trifluoromethyl) alcohols; anti diastereomers were formed as major products in the trifluoromethylation reaction whereas syn diastereomers were obtained as single isomers in a two-step procedure. Swern oxidation of the mixtures formed in the trifluoromethylation leads to the corresponding α-dibenzylamino trifluoromethyl ketones which undergo diastereoselective reduction with sodium borohydride.
