New Advances in Chemical Research, April 2021. Catalysts are in the same phase as the reactants. Enzymes are biological catalysts that produce large increases in reaction rates to be specific for certain reactants. Introduce a compound,318276-74-3, Name is Methyl cinnoline-6-carboxylate. 318276-74-3
A solution of the compound from example 3d) (345 mg; 1.8 mmol.) in anhydrous tetrahydrofuran (20.0 mL) was cooled to 5 oC for the portionwise addition of solid lithium aluminumhydride (70.0 mg; 1.8 mmol.) and stirred at 5 0C for 1 h. The mixture was quenched by the addition of ethyl acetate (50.0 mL) then water (5.0 mL), filtered through a pad of Celite and evaporated. The residue was dissolved in ethyl acetate (50.0 mL) and treated with manganese dioxide (0.50 g) and stirred at room temperature for 2 h. The mixture was filtered through a pad of Celite and evaporated to afford the title EPO
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 13889-98-0, help many people in the next few years.318276-74-3
