Yield:68-26-8 99%
Reaction Conditions:
with sodium tetrahydridoborate in methanol at 20; for 0.25 h;Darkness;Temperature;
Steps:
14-15
To the dry reaction tube were added retinal (1aa, 57.0 mg, 0.2 mmol) and methanol (1 mL), and sodium borohydride (15.2 mg, 0.4 mmol) was added with stirring. The mixture was stirred at room temperature for 15 minutes in the dark. Water (5 mL) was added to quench the reaction, and the mixture was extracted with ethyl acetate (4 x 5 mL). The organic phases were combined, washed twice with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, filtered, and the solvent was removed by rotary evaporation to obtain vitamin A (2aa, 57.1 mg, 99%): yellow liquid;
