α-nitro esters via the trapping of nitronium ions. The two-stage nitration and subsequent deacetylation of readily available 1,3-dicarbonyl compounds was achieved using a biphasic semicontinuous approach. α-Nitro esters and amides were obtained in good overall yields (53–84%). Some of the α-nitro-1,3-dicarbonyl intermediates exhibit enhanced reactivity and undergo an acid-catalyzed Nef-type reaction to

Ethyl alpha-halo-alpha-nitropropionate and -butyrate were prepared by alkylating ammonium salts of ethyl bromo- and chloronitroacetates. The addition of alkyl acrylates to alkyl chloronitroacetates or their salts gives dialkyl alpha-chloro-alpha-nitroglutarates. Sodium salts of ethyl alpha-nitro-alpha-sulfo-beta-hydroxypropionate and -butyrate were obtained by the sulfo-dehalogenation of ethyl alpha-chloro-alpha-nitro-beta-hydroxypropionate and -butyrate with sodium dithionite. Esters of a-amino acid hydrochlorides were prepared by the reduction of alkyl alpha-chloro-alpha-nitrocarboxylates. The hydrogenation of alkyl nitrosulfoacetates leads to the corresponding disodium salts of alkyl aminodisulfoacetates and piperazine-2,5-dione.
