Research speed reading in 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, new energy materials, preparation and modification of special coatings. Introduce a common compound, CAS is 875-66-1, Name is Cinnolin-4-ol, belongs to cinnoline compound. 875-66-1
Example 20: Synthesis of 1- [4- (5-FLUORO-2-METHOXYPHENYL)-2-HYDROXY-4-METHYL-2- TRIFLUOROMETHYLPENTYL]-LH-CINNOLIN-4-ONE To a suspension of 2- [2- (5-fluoro-2-methoxyphenyl)-2-methylpropyl]-2-trifluoromethyloxirane (216 mg) and cinnolin-4-ol (V. G. Chapoulaud et AL., Tetrahedron, 2000,56, pp. 5499-5507) (216 mg) in anhydrous ethanol (1.2 ML) was added sodium ethoxide (21 wt. % solution in ethanol, 276 PL). After heating at 85C for 16 hours, the reaction mixture was diluted with ethyl acetate, dried over sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by preparative TLC (eluted with 40% ethyl acetate-hexanes) to give the title compound as a pale yellow solid (26 mg), m. p. 122C-123C.
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about 875-66-1 is helpful to your research. 875-66-1
