Certain .alpha.-(fluoromethyl or difluoromethyl)-.alpha.-aminoacetonitriles are prepared by treating the appropriate .alpha.-(fluoromethyl or difluoromethyl) ketimine magnesium halide with hydrogen cyanide or with an alkali metal cyanide or ammonium cyanide and a proton source. The products are useful as intermediates for making .alpha.-(fluoromethyl or difluoromethyl)-.alpha.-amino acids having pharmacological activity.
某些α-(氟甲基或二氟甲基)-α-氨基乙腈是通过将相应的α-(氟甲基或二氟甲基)酮亚胺镁卤化物与氢氰酸或与碱金属氰化物、氰化铵及质子源反应制备而成。这些产物作为中间体,可用于合成具有药理活性的α-(氟甲基或二氟甲基)-α-氨基酸。
