The corresponding 4-acetylamino-2-thiophenecarboxylic acids or their esters were produced by the action of reduced iron on solutions of 4-nitro-2-thiophenecarboxylic acid, its derivatives, or their esters in a mixture of acetic acid and acetic anhydride. Esters of 5-acetylamino-2-thiophene...

Condensation of ethyl 2,4-dioxopentanoate with ethyl trifluoroacetate in the presence of NaOEt leads to ethyl 4-oxo-6-(trifluoromethyl)-4 H -pyran-2-carboxylate, from which the corresponding acid and its amide, as well as 4-hydroxy-6-(trifluoromethyl)pyridine-2-carboxamide were obtained....
fraction. Mitochondrial proteins accounted for 59% of all proteins and 64% of all acetylation sites identified; the proteins were strongly associated with fatty acid metabolism enzymes, oxidative phosphorylation and the tri-carboxylic acid cycle. These proteins usually contained more than one acetylation...
This intermediate contains both hydroxyl and carboxylic acid groups, and it was then subjected to macrolactonization condition in the presence of benzotriazol-1-yloxytripyrrolidinophosphonium hexafluorophosphate (PyBOP) and DMAP, providing the macrolactone 658 smoothly. The DIBAL-H mediated reductive ...
The major phenazine compound was shown to be PCN (84%), followed by the intermediate product phenazine-1-carboxylic acid (PCA, 16%) (Fig. 2e). The growth inhibitory activities of these two phenazine compounds toward Fg were determined in vitro. As shown in Fig. 2f, g, PCN was more ...
The absence of the peak in the region 1850–1760 cm−1 implied that the product was free of unreacted acetic anhydride, and the absence of absorption in the area of 1700 cm−1 for the carboxylic group indicated that the product was also free of acetic acid byproduct; the same observati...
