(S)-(+)-2-氨基庚烷

反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A sample of 0.15 mL (1 mmol) of (S)-(+)-2-aminoheptane ((S)-44) 0.1 mL (1 mmol) of benzaldehyde and 0.1 mL of HOAc were combined in 10 mL of CH2Cl2 and cooled to 0° C., then added 650 mg (3 mmol) of sodium triacetoxyborohydride in one portion. The reaction mixture was stirred under argon at room temperature for 28 hours. The mixture was diluted with 10 mL of dichloromethane, cooled in an ice bath and 20 mL of 5% NaOH (in water) was added. Fractions were separated, organics were dried (Na2SO4) and evaporated to 154 mg (70%). 1H NMR (CDCl3) 600.88 (m, 3H), 1.08 (d, 3H J=6.6 Hz), 1.19-1.37 (m, 6H), 1.41-1.67 (m, 2H), 3.62-3.77 (m, 1H), 3.75 (p, 2H, J=12 Hz), 7.17-7.41 (m, 5H); MS (APCI+) m/z (rel): 206 (100); [α]D=+7.8° (c=1.0, MeOH). cooled in an ice bath Fractions were separated organics were dried (Na2SO4) evaporated to 154 mg (70%)
