Related Products of 56-81-5, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.56-81-5, name is Propane-1,2,3-triol, molecular formula is C3H8O3, molecular weight is 92.0938, as common compound, the synthetic route is as follows.
To a 1,4-dioxane solution (200 mL) containing glycerol(18.4 g, 0.20 mol) and vinyl benzoate (29.6 g, 0.20 mol),Lipozyme (30 g) was added, and the mixture was stirred for48 h at 55C. After removal of the enzyme by filtration, thereaction mixture was evaporated under reduced pressure andthe residue was partitioned between saturated brine and dichloromethane(100 mL each), and extracted with dichloromethane(3 60 mL). The combined organic layer waswashed with saturated brine, and dried over anhydrousNa2SO4. The extract was washed with hexane to removeunreacted vinyl benzoate. Subsequently, the extract was vacuumdried, affording 36 g of (±)-1 (75% yield) as a colorlessoil.
