Name is (S)-Butane-1,3-diol, as a common heterocyclic compound, it belongs to chiral-oxygen-ligands compound, and cas is 24621-61-2, its synthesis route is as follows.,24621-61-2
To a solution of (S)-1,3-butanediol (807 mg) in DMF (10 mL) at 0C was added potassium t-butoxide (7.2 mL of a 1M solution in THF). After 1 h, the mixture was cooled to -20C and then 2-chloro-3-(4-methylsulfonyl)phenyl-5-trifluoromethylpyridine (1 g) was added as a solid. The resulting mixture was stirred for 24 h, warming to r.t. To the mixture was added saturated NH4Cl and the mixture was extracted with ethyl acetate. The organics were dried (MgSO4) and concentrated. Flash chromatography (1:1 hexane/ethyl acetate) provided the title compound as a white solid (323 mg).1H NMR (300 MHz, acetone-d6): d 1.15 (d, 3H), 1.75-2.00 (m, 2H), 3.15 (s, 3H), 3.65 (d, 1H), 3.85-4.00 (m, 1H), 4.60 (dd, 2H), 7.95 (d, 2H), 8.03 (d, 2H), 8.10 (d, 1H), 8.57 (d, 1H).
With the complex challenges of chemical substances, we look forward to future research findings about (S)-Butane-1,3-diol
