Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials. 318276-74-3. Introduce a common compound, CAS is 318276-74-3, Name is Methyl cinnoline-6-carboxylate, belongs to cinnolinecompound.
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 compound (169 mg; 60%) as a brown powder which was used directly in the following step without further purification
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about Methyl cinnoline-6-carboxylate is helpful to your research. 318276-74-3
