As a common heterocyclic compound, it belong chiral-oxygen-ligands compound,(S)-Butane-1,3-diol,24621-61-2,Molecular formula: C4H10O2,mainly used in chemical industry, its synthesis route is as follows.
To a solution of commercial available (s)-3-hydroxy butanol (10 g, Aldrich) in 50 mL of DMF, TsOH (20 mg, catalytic) and MeOPhCH (OMe) 2 (24 g) were added. After 3h at 35 C on a rotovap with slight vacuum, it was cooled and quenched with aq. Sat. NaHC03. The mixture was extracted with EtOAc (3x). The organic layers were washed with brine (2x), dried and concentrated. The crude product was evaporated with toluene (3x). [0230] The crude product was dissolved in 700 mL of CH2CI2. At 0 C, DIBAL-H solution (200 mL, 1.0 M, excess) was added. The reaction was warmed to room temperature overnight. Then it was quenched with methanol (50 mL), sat. Na2S04 at 0 C. The mixture was diluted with Et20 (1. 5L). After stirred for 5h, it was filtered through a pad of celite. The filtrate was concentrated to give an oil. The oil was purified on silica gel with Hexanes/EtOAc, 10: 1,6 : 1,3 : 1, and 1: 1 to give 24 g of desired product, 343-YW-203
With the synthetic route has been constantly updated, we look forward to future research findings about (S)-Butane-1,3-diol,belong chiral-oxygen-ligands compound
