As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 24621-61-2,(S)-Butane-1,3-diol, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.24621-61-2
To a solution of (S)+}1,3-butanediol (10.0 g, 0.110 mol), was added triphenylmethylchloride (33.0 g, 0.330 mol), 4-dimethylaminopyridine (1.40 g, 11.5 mmol) in CH2Cl/pyridine (1:1, 500 mL).Stirring was continued over 48 h. The solvent was removed, the mixture was diluted with ether, washed with brine and dried over Na2SO4. The organic solution was filtered and concentrated. Silica gel chromatography with (5% ethyl acetate/hexanes) produced a clear oil (24 g) in 70% yield., 24621-61-2
