Reductive Dimerization of Alkylidenemalonates Using Samarium(II) Diiodide and ^1H-NMR Behavior of the Dimers, 2,3-Diaryl-1,1,4,4-butanetetracarboxylates
スポンサーリンク
概要
- 論文の詳細を見る
Alkylidenemalonates were readily dimerized in the presence of SmI_2 to give 2,3-disubsituted 1,1,4,4-butanetetracarboxylates as mixtures of meso and racemic isomers in moderate to good yields. The structure of the less polar isomer of tetraethyl 2,3-diphenyl-1,1,4,4-butanetetracarboxylate was determined by X-ray crystallographic analysis to be the meso form. Characteristic ^1H-NMR behavior of the meso and racemic isomers is also discussed.
