  无金属的脱羧杂-Diels -3-羟基吡啶的Alder合成：快速获得N-融合的双环羟基哌啶骨架

  摘要：

  报道了5-烷氧基恶唑与丙烯酸热控制的无金属脱羧杂狄尔斯-阿尔德（HDA）反应的完整实验和理论研究。该策略为易于获得的2-和4-二取代的5-烷氧基恶唑提供了有价值的2,6-二官能化的3-羟基吡啶的新入口。证明该反应条件尤其与酮，酰胺，酯，醚和腈基相容。该方案具有广泛的官能团耐受性，可通过吡啶脱芳构化策略快速而通用地获得羟基吲哚并咪唑和羟基喹oli嗪衍生物。

  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.
