Reaktionsschritte
In a preferred embodiment, a method for producing 2-nitro-1-phenyl-1-propanol is provided. This method comprises reacting benzaldehyde with nitroethane in the presence of an amine catalyst. The 2-nitro-1-phenyl-1-propanol produced by this reaction has a (1R*,2S*) stereoisomer and a (1R*,2R*) stereoisomer. The preferred (1R*,2S*) stereoisomer makes up greater than about 50% of the 2-nitro-1-phenyl-1-propanol. Reduction of this nitro-alcohol produces dl-norephedrine in high yield.
