In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 24621-61-2,(S)-Butane-1,3-diol, as follows.24621-61-2
(S)-(+)-Butane-1 ,3-diol (3.00 mmol, 0.270 g) was added to a stirred solution of imidazole (5.99 mmol, 0.41 g) and tert-butyldimethylsilyl chloride (3.00 mmol, 0.45 g) at room temperature. After six hours at room temperature water (50 mL) was added and extracted twice with dichloromethane (20 mL). The combined organic extracts were washed with brine, dried (sodium sulfate) and concentrated in vacuo to yield (S)-4- (tert-butyldimethylsilyloxy)butan-2-ol (0.654 g).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. 24621-61-2, We look forward to the emergence of more reaction modes in the future.
