Nitration of styryl ketones with nitrogen peroxide leads to the corresponding α-nitroethylenic ketones in good yield. However, the presence of methoxy groups involves a nitration on the aromatic nucleus. LiAlH4 reduction of α-nitrostyrylketones yields the corresponding racemic erythro-and threo-aminoalcohols; after acylation and cyclisation a dihydro-quinoline or a 2- oxazoline is obtained. Electrochemical reduction of these nitrostyryl-ketones selectively ...
