Baeyer–Villiger Oxidation of Cyclobutanones with 10-Methylacridinium as an Efficient Organocatalyst
Baeyer–Villigeroxidation of cyclobutanones is achieved in current developed protocol with 10-methylacridinium perchlorate (AcrH+ClO4−) as a novel organocatalyst both with irradiation at room temperature and without irradiation at elevated temperature. Excellent yields of the corresponding lactones are obtained and the possible mechanism has been proposed.
N'-dioxide-Sc(III) complex catalysts. The BV oxidations of prochiral cyclohexanones and cyclobutanones afforded series of optically active ε- and γ-lactones, respectively, in up to 99% yield and 95% ee. Meanwhile, the kinetic resolution of racemic 2-arylcyclohexanones was also realized via an abnormal BV oxidation. Enantioenriched 3-aryloxepan-2-ones, whose formation is counter to the migratoryaptitude, were

A new type of coupling between unactivated olefins and nonstabilized alkyl radicals was achieved, which enabled the first intermolecularHeck-typereaction of cycloketone oxime esters and unactivated alkenes. This directing-group-based strategy was compatible with various unactivated alkenes and cyclobutanone-, cyclopentanone-, and cyclohexanone-derived oxime esters. Density functional theory calculations
