Methanol → HCID 117643490, compound

Participants

Reaction Steps

A methanol solution (10 ml) containing sodium borohydride (1.5 g) and (S)-2-(dibenzylamino)-5-methyl-4-hexen-3-one (4.2 g) obtained in the 3rd step were added to an MeOH (30 ml) solution containing cerium chloride (10 g), followed by stirring for 7 hours. Water was added to the reaction solution, followed by extraction with ethyl acetate. The organic layers were washed with water and saturated saline and dried over anhydrous sodium sulfate. Then, the solvent was distilled away under reduced pressure and the obtained residue was purified by silica gel chromatography (n-hexane:ethyl acetate=1:0 to 1:0.2). A yellow liquid of (2S)-2-(dibenzylamino)-5-methyl-4-hexen-3-ol (3.5 g) was thus obtained.
