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.96-35-5, name is Methyl 2-hydroxyacetate, molecular formula is C3H6O3, molecular weight is 90.08, as common compound, the synthetic route is as follows.SDS of cas: 96-35-5
Intermediate 4: 4-oxotetrahydrofuran-3-carbonitrile [00211] To a solution of potassium tert-butoxide (24.91g, 222.O3mmol) in THF (200mL) at 0Cwas added methyl glycolate (20.OOmL, 259mmo1) dropwise. The mixture was left to stir for 10 minutes before adding acrylonitrile (14.62mL, 222mmo1) dropwise. The reaction then allowed to warm to room temperature and left to stir for 3 hours. Water and EtOAc were added to the reaction mixture and the layers separated. The aqueous layer as then acidified to pHi with 1 M HCI and extracted twice with EtOAc. The combined organic layers were then washed with brine, dried over Na2SO4 and then passed through a hydrophobic frit before being concentrated under reducedpressure to afford 4-oxotetrahydrofuran-3-carbonitrile (10.29g, 93mmol, 42% yield) as a yellow solid.1H NMR (CDCI3, 400MHz) O/ppm: 4.65 (1H, t, J= 9.3Hz), 4.26 (1H, t, J= 9.3Hz), 4.18 (1H, d, J=17.5Hz), 4.02 (1H, d, J= 17.5Hz), 3.61 (1H, t, J= 9.3Hz).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,96-35-5, Methyl 2-hydroxyacetate, and friends who are interested can also refer to it.
