Substitution of halogen atom in ?-halonitro compounds of the aliphatic series
摘要:
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.
