As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 534-03-2, name is 2-Aminopropane-1,3-diol, molecular formula is C3H9NO2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Application In Synthesis of 2-Aminopropane-1,3-diol
(1) N-(4-Phenoxybenzenesulfonyl)serinol After triethylamine (10.12 g, 100 mmol) was added dropwise to a solution of serinol (3.64 g, 40 mmol) in a mixture of dioxane (100 ml) and water (200 ml), the mixture was stirred at room temperature for 30 minutes.. To the reaction mixture, a solution of 4-phenoxybenzenesulfonyl chloride (10.75 g, 40 mmol) in dioxane (100 ml) was added dropwise and this was stirred for 3 hours.. Most of the solvent was evaporated under reduced pressure and the residue was extracted with ethyl acetate.. The organic layer was washed with water, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to afford the desired compound (10.62 g, yield 82%) as a white powder. 1H-Nuclear magnetic resonance spectrum (400 MHz, CDCl3-DMSO-d6) delta ppm: 7.84 (2H, d, J=8 Hz), 7.41 (2H, t, J=8 Hz), 7.22 (2H, t, J=7 Hz), 7.09-7.01 (4H, m), 6.69 (1H, d, J=7 Hz), 4.10-4.06 (1H, m), 3.63-3.45 (4H, m).
With the rapid development of chemical substances, we look forward to future research findings about 534-03-2.
