反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: In a 50 mL-volumetric autoclave were added deaerated methanol (10 mL) and t-amyl alcohol (10 mL), and thereto were added 4-aminopyridine (47 mg, 0.5 mmol) and (S)-methylglycidyl ether (1.8 g, 20 mmol, >99% ee). Then to the mixture was added crystalline dicobaltoctacarbonyl complex (171 mg, 0.5 mmol). After covering the autoclave with a cap, carbon monoxide (1 MPa) was introduced therein and the mixture was reacted at 40° C. for 8 hours. After cooling to room temperature, the solvent was removed in vacuo. The residue was subjected to Kugelrohr distillation to give (S)-4-methoxy-3-hydroxybutanoic acid methyl ester (2.7 g, 92%, >99% ee) as a colorless oil. was introduced the mixture was reacted at 40° C. for 8 hours the solvent was removed in vacuo The residue was subjected to Kugelrohr distillation

実験手順: A solution of (S)-methyl glycidyl ether (10 g) and benzylamine (3.62 g) in methanol (50 ml) was stirred at 55° C. for 2 hours. To the mixture was added (S)-methyl glycidyl ether (1 g), and the mixture was stirred at 55° C. for 2 hours, and then evaporated under reduced pressure. Toluene was added to the residue and evaporated under reduced pressure to give (2S)-1-[N-benzyl-N-[(2S)-2-hydroxy-3-methoxypropyl]amino]-3-methoxypropan-2-ol (8.84 g) as a pale yellow oil. evaporated under reduced pressure Toluene was added to the residue evaporated under reduced pressure
