  • Reductive alkylation of amines can be effected with NaBH4/formaldehyde; see e.g.: Synthesis, 743 (1980); or TFA: Synthesis, 709 (1987). See also Sodium cyanoborohydride, 87839. Reductive alkylation of aromatic amines with a variety of aldehydes and ketones has been reported, using NaBH4/H2SO4: Synthesis, 121 (1993).
  • The reduction of aldehydes and ketones to alcohols occurs in alcoholic or aqueous media. For highly selective reduction of aldehydes in the presence of ketones, see: Synth. Commun., 18, 1927 (1988). For enantioselective reduction, see L-tert-Leucine, L13707. Borohydride reductions can be carried out in organic solvents, e.g. toluene, under phase-transfer conditions, amenable to scale-up: Org. Process Res. Dev., 1, 287 (1997).
