Fatty acid phenyl-substituted

Oxidation of higher fatty acids was first studied in 1904 by Knoop who fed animals with phenyl-substituted fatty acids and analyzed the products in the urine. He showed that the fatty acid oxidation results in the successive cleavage of two carbon moieties from the carboxyl end. Knoop coined the fatty acid oxidation mechanism as n-oxidation. As has been established by Kennedy and Lehninger in 1948-1949, oxidation of fatty acids occurs in the mitochondria only. Lynen and coworkers...

Additionally, Rivkin and co-workers synthesized a variety of 4-hydroxy-3-phenylquinolin-2-(l//)-ones under solvent free microwave conditions using an activated arylmalonate <06TL2395>. Reacting the desired substituted aniline with di-(2,4,6-trichlorophenyl)-2-phenyl-malonate at 250 °C with microwave irradiation for 15 min resulted in a variety of 4-hydroxy-3-phenylquinolin-2-(l//)-ones in good yields. They also demonstrated the utility of this method in the synthesis of type I fatty acid synthase inhibitors <06BMCL4620>. Kumar et al. have reported a variation of the Friedlander quinoline synthesis. They highlight the use of CeClj THjO as a reusable catalyst in the reaction of 2-... 

Substituted derivatives of 7-phenyl-l-(oxazol-2-yl)heptane-l-one (113) have been shown to inhibit the enzyme fatty acid amide hydrolase with inhibition constants as shown Table 6.17. Predict the fCj value of the 5-trifluoromethyl derivative. 

According to Kolbe a monobasic acid is formed by substituting an equivalent of oxygen outside the radical of carbonic acid by hydrogen (giving formic acid), or an alcohol radical (giving fatty acids), or phenyl (giving benzoic acid).
