Using ethyl acetate as the ideal solvent, with an ozone: fluorene molar ratio of 1.6:1 and reaction duration of 90 min, optimal conditions for ozone oxidation resulted in a 66% yield of 9-fluorenone. We also postulated the chemical mechanism involved in fluorine oxidation by ozone. The ...
A mixture of 9-fluorenone, phenol-d5 and b-mercaptopropionic acid was added to a 50 ml three-neck bottom flask equipped with a magnetic stirrer, reflux condenser and thermometer, and then concentrated sulphuric acid was slowly added dropwise with stirring. The mixture was heated at 55 °C ...

Chemical Synthesis—α-CTx PeIA (0.45 mmol/g) was synthesized on an amide resin using Fmoc (N-(9-fluorenyl)methoxycarbonyl) chemistry and standard side protection, except on cysteine residues. Cys residues were protected in pairs with either S-trityl on Cys2 and Cys8, or S-acetamidomethyl ...
The term "tricyclic aryl" as used herein includes anthracenyl, phenanthrenyl, biphenylenyl, fluorenyl, and the like. Aryl groups (including bicyclic and tricyclic aryl groups) can be unsubstituted or substituted with one, two or three substituents independently selected from loweralkyl, haloalkyl,...
