aldehydes, ketones and esters β-carbonyl radicals can be generated via enolization, cyclopropanation, solvomercuration and reduction with NaBH4. Radicals react with electron-poor alkenes to give products of CC-bond forming reactions (Tables 1–3). Carbonyl compounds are therefore precursors of three-carbon building blocks. The products result from reactions with “Umpolung”.
通过醛化,环丙烷化,溶剂化和NaBH 4还原,可以从醛,酮和酯生成β-羰基自由基。自由基与贫电子烯烃反应生成CC键形成反应的产物(表1-3)。因此,羰基化合物是三碳构件的前体。产物来自与“ Umpolung”的反应。
