Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): CYCLIZATION -- CYCLOPROPANE-1,2-DICARBOXYLIC ACID -- GLUTAMIC ACID -- TRANSESTERIFICATION Аннотация: The kinetics of the reactions of alkyl N-phthaloyl-4-bromoglutamates with Et3N and KOH was investigated. The reactions proceed stercospecifically to form alkyl 1-phthalimido-cyclopropane-r-1-2-dicarboxylates. In alcohols, the reactions are accompanied by transesterification. The concerted mechanism accounting for the stereospecificity of these reactions is proposed. \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2001, 50 (4), 644.pdf |
