Application of 14002-80-3 ,Some common heterocyclic compound, 14002-80-3, molecular formula is C6H12O3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
LiOH (15.9 g, 37.9 mmol) in THF/MeOH/H2O (1:1:0.5, 62.5 mL) was added to a solution of 3-hydroxy-2,2-dimethylpropionate 14 (5 g, 37.9 mmol) in THF/MeOH (1:1, 25 mL) at 0 C. The solution was warmed to rt and stirred for 1.5 h, the reaction mixture was adjusted to pH 2 by addition of H2SO4. The solution was concentrated under reduced pressure to remove THF and the residue washed with H2O (10 mL), extracted with EtOAc (3 12 mL), dried over Na2SO4 and concentrated under reduced pressure to give the acid (3.3 g, 27.9 mmol, 73%) as a white solid. Benzyl bromide (1.9 mL, 16.1 mmol) was added to a solution of crude acid (2.0 g, 16.9 mmol) and K2CO3 (2.57 g, 18.6 mmol) in DMF (20 mL). The reaction mixture was stirred for 5 h then quenched by the addition of H2O (5 mL). The reaction mixture was extracted with Et2O (3 10 mL). The combined organic extracts were washed with brine (10 mL), dried over Na2SO4 and concentrated under reduced pressure. Purification by column chromatography using 9:1 to 3:2 hexanes/EtOAc as eluent gave the title compound 20 (3.04 g, 86%) as a yellow oil.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,14002-80-3, its application will become more common.
