A golden opportunity: Benzofuranone modifications of aurones and their influence on optical properties, toxicity, and potential as dyes

Aurones are a small subclass of the flavonoid family known primarily for their unusual structure and the golden yellow color they impart to the flowers of snapdragons and cosmos. Most studies of aurones focus on their range of biological activities, but relatively little has been reported with respect to their optical properties, unlike their aza and thio analogs. What little is known has focused entirely on the influence of the benzylidene portion. In this study, the influence of substitution in the benzofuranone ring on the UV-vis spectrum is explored, as well as an initial screening of their toxicity and a qualitative preliminary study of their potential to act as fabric dyes.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 519018-52-1 is helpful to your research. Related Products of 519018-52-1

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.519018-52-1,7-Bromobenzofuran-3(2H)-one,as a common compound, the synthetic route is as follows.

519018-52-1, Reference Example 687-bromo-2, 3-dihydro-l-benzofuran-3-amine; [0397]A mixed solution of 7-bromo-l-benzofuran-3 (2H) -one (0.521 g, 2.45 mmol) , 0-methylhydroxyammonium chloride (0.306 g, 3.67 mmol) and sodium acetate (0.301 g, 3.67 mmol) in methanol (12 mL) was heated under reflux for 10 hr, and the mixture was stirred at room temperature for 16 hr. The reaction mixture was concentrated’ under reduced pressure, the residue was poured into saturated aqueous sodium hydrogen carbonate, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane: ethyl acetate = 100:0 – 80:20) to give 7-bromo-l-benzofuran-3 (2H) -one O- methyloxime (0.468 g, yield 79%) as a yellow solid. To a solution of 7-bromo-l-benzofuran-3 (2H) -one O-methyloxime (0.468 g, 1.93 mmol) obtained above in tetrahydrofuran (9 mL) was slowly added dropwise borane-tetrahydrofuran solution (1 M, 5.80 mL, 5.80 mmol) at room temperature, and the mixture was heated under reflux under a nitrogen atmosphere for 3 hr. The reaction mixture was cooled, ice water was slowly added, 1 M hydrochloric acid was added, and the mixture was stirred at8O0C for 1.5 hr. The reaction mixture was allowed to cool, 28% aqueous ammonia solution was added to alkalify the solution, and the mixture was extracted with ethyl acetate. The extract was dried over sodium sulfate, and concentrated under reduced pressure. The residue (0.402 g) was dissolved in diethyl ether (4 mL) , and 4 M hydrochloric acid-ethyl acetate solution (0.480 mL) was slowly added. The precipitated solid was collected by filtration, and washed with diethyl ether to give 7-bromo-2, 3-dihydro-l-benzofuran-3-amine hydrochloride (0.434 g) as a beige solid. The solid obtained above was dissolved in28% aqueous ammonia solution, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over sodium sulfate, and concentrated under reduced pressure to give the title compound (0.366 g, yield 89%) as a yellow solid.1H NMR (300 MHz, DMSO-d6) delta 2.15 (2H, br s), 4.05-4.16 (IH, m) , 4.58-4.72 (2H, m) , 6.78-6.87 (IH, m) , 7.28-7.38 (2H, m) .

As the paragraph descriping shows that 519018-52-1 is playing an increasingly important role.
