Duisberg, Chem.The compounds such as 3—acetylcoumarin, 3—acetyl—7— diethylamino photosynthesis, and 7— diethylamino —3— 1—oxobutyl coumarin were synthesized by KCR method which involved the condensation of salicylaldehyde or 4— diethylamino salicylaldehyde with ethyl acetoacetate, 4— diethylamino — salicylaldehyde song ethyl butyrylacetate in the presence of dimethylamine as a catalyst. Meanwhile, 7—hydroxy—4—methylcoumarin, 4—methyl—2H—benzo[h]chromen—2—one, 7—hydroxy—4,8—dimethyl— coumarin, 7—hydroxy—4—propylcoumarin, 4—propyl—2H—benzo[h]chromen—2—one, 7—hydroxy—8—methyl—4—propylcoumarin and 7,8—dihydroxy—4—propylcoumarin were synthesized through Pechmann warming reaction by condensation of resorcinol, 1—napthol or 2—methylresorcinol with ethyl acetoacetate, and resorcinol, Asus zenbook ux32la review journal newspaper, 2—methylresorcinol or pyrogallol with ethyl butyrylacetate, related in the presence of sulphuric acid as a catalyst. All compounds were characterized by spectroscopic techniques using infrared IRhomework and carbon nuclear magnetic resonance 1H and 13C NMR.

Help writing personal statementAfter the reaction was completed, the mixture was extracted with EtOAc 3 x 15 mL. The organic phase was separated and dried over anhydrous sodium sulfate and rotary evaporated to dryness with a vacuum pump. The hydrolysis of the ester was followed by thin layer chromatography TLC. Once completed, the reaction mixture was washed 3 x 15 mL of brine in a separation funnel and the organic phase was separated, dried over anhydrous sodium sulfate, and then taken to dryness using a rotary evaporator and a vacuum pump. Subsequently, 6 equivalents of thionyl chloride and 4 equivalents of isopropanol or n-butanol were added. This reaction mixture was set to reflux for 4 hours. The reaction was monitored by TLC. Anti-inflammatory Evaluation of 1b A preliminary exploration of the anti-inflammatory effect of compound 1b, was assayed by the carrageenan induced paw edema in rat. The rats were kept fasted for 12 hours before the experiment. A set of 6 animals was treated as control group. After the administration of the correspondent dose of 1b, edema was induced in the right hind paw by intradermal injection of 0. Prior to this, the paws were measured by a Hugo Basille digital pletismometer, then measurements were made every hour during six hours of the experiment. Throughout this process, the animals had free access to water. The results of the maximum protective effect were performed on Sigma Plot Results and Discussion 3. Mir, M. Martinez, Food Chem.
