Abstract: Nitrones are produced by reaction of primary amine with aldehyde or ketone, in the presence of a transition metal-containing oxidation catalyst, and a peroxidic compound. The nitrone can then be reacted with a vinylaromatic compound to produce a 2-hydrocarbyl-5-arylisoxazolidine. Both such reactions can be conducted concurrently by including the vinylaromatic compound in the initial reaction mixture. Hydrogenation of the 2-hydrocarbyl-5-arylisoxazolidine, e.g., using hydrogen and a palladium-carbon catalyst, forms an N-hydrocarbyl-3-aryl-3-hydroxypropylamine. Such reactions enable, inter alia, synthesis of the racemic hydrochloride salt of N-methyl-3-phenyl-3-[4-trifluoromethyl)phenoxy]-propylamine, known generically as fluoxetine hydrochloride, a widely used antidepressant.
