24621-61-2 A common heterocyclic compound, 24621-61-2,(S)-Butane-1,3-diol, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Triethylamine (1.173 g) is added dropwise to a solution of 2.246 g triisopropylchlorosilane and 1 g (S)-(+)-1,3-butanediol in 15 ml of dry tetrahydrofuran. The mixture is stirred for 48 hours at room temperature, then is diluted with 400 ml of tert-butyl methyl ether and washed respectively with 30 ml 1N HCl, 50 ml water and 50 ml of brine. The organic phase is dried (sodium sulphate), filtered and evaporated to dryness. The residue is purified by means of flash column chromatography (SiO2 60F) to provide the title compound as a colorless oil. Rf=0.31 (EtOAc-heptane 1:5).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand 24621-61-2 reaction routes.
