Reference of 90030-48-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 90030-48-1, name is Sodium 3-methoxy-3-oxopropane-1-sulfinate belongs to esters-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
A solution of Intermediate 67 tert-butyl ((5-bromo-1H-pyrrolo[3,2-b]pyridin-2- yl)methyl)(methyl)carbamate (1.1912 g, 3.50 mmol), sodium 3-methoxy-3-oxopropane-1-sulfinate (1.224 g, 7.03 mmol, Aldrich) and copper(I) iodide (1.34 g, 7.04 mmol) in Dimethyl Sulfoxide (DMSO) (18 ml) was degassed for 10 minutes under a flow of nitrogen. The reaction vessel was heated to 110 C and stirred at 110 C under nitrogen for 2h. Ethyl acetate (30 ml) was added to the reaction mixture, which was then filtered on Celite (lOg) and the residual solid washed with ethyl acetate (3×20 ml). The filtrate was washed with a mixture of water/aqueous saturated ammonium chloride / aqueous saturated sodium bicarbonate (4: 1: 1 60 ml), and water (60 ml). The aqueous layer was further extracted with ethyl acetate (50 ml) and the organic phases combined. The organic phase was further washed with a mixture of water/aqueous saturated ammonium chloride / aqueous saturated sodium bicarbonate (4: 1: 1 60 ml), and water (60 ml), followed by brine (50 ml), dried over magnesium sulfate and concentrated under reduced pressure to yield methyl 3-((2- (((tertbutoxycarbonyl)(methyl)amino)methyl)-1H-pyrrolo[3,2-b]pyridin-5-l)sulfonyl)- propanoate (1380 mg, 3.35 mmol, 96% yield). LCMS (System B, UV, ESI): Rt = 0.92 min, [M+H]+ 412
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Sodium 3-methoxy-3-oxopropane-1-sulfinate, other downstream synthetic routes, hurry up and to see.
