C–C coupling of alkyl and trialkylsilyl nitronates with silyl keteneacetals yields functionalized nitroso acetals. This conversion may serve as a new simple procedure to reverse the conventional reactivity of aliphatic nitro compounds. Preliminary results on the hydrogenation of nitroso acetals into amino acids derivatives, as well as TFA-catalyzed transformations of nitroso acetals, are examined to
