It is a common heterocyclic compound, the chiral-oxygen-ligands compound, (S)-Butane-1,3-diol, cas is 24621-61-2 its synthesis route is as follows.,24621-61-2
General procedure: (R)-Ethyl 3-hydroxybutyrate (2.1 g, 16 mmol) and (R)-1,3 butanediol(1.0 g, 11 mmol) were combined and incubated with CAL-B (0.2 g,400 U) at 80 torr without solvent in a rotary evaporator. The reaction was monitored by withdrawing 5 muL portions of the reaction mixture,which were dissolved in 1.0 mL methanol for analysis by GC-MS. Upon consumption of the diol, the reaction mixture was taken up in dichloromethane,the beads were filtered and washed, and the solventremoved by rotary evaporation. Excess (R)-ethyl 3-hydroxybutyratewas removed by heating to 60 deg C under reduced pressure (1 torr).The residue was suspended in ethyl acetate, treated with activated carbon and filtered to yield (R)-3-hydroxybutyryl-(R)-3-hydroxybutyrateas a clear oil (1.2 g, 62%).
With the complex challenges of chemical substances, we look forward to future research findings about (S)-Butane-1,3-diol
