Synthesis of Dihydropyrroles by the Intramolecular Addition of Alkylideneaminyl Radicals Generated from O-2,4-Dinitrophenyloximes of γ,δ-Unsaturated Ketones
Alkylideneaminyl radicals are generated from O-2,4-dinitrophenyloximes of γ,δ-unsaturated ketones by treatment with NaH and 3,4-methylenedioxyphenol. The resulting radical species successively add to the olefinic moiety intramolecularly to afford 3,4-dihydro-2H-pyrroles.
通过用 NaH 和 3,4-亚甲二氧基苯酚处理,从 γ,δ-不饱和酮的 O-2,4-二硝基苯基肟生成亚烷基。产生的自由基物质依次分子内加成到烯烃部分,得到 3,4-二氢-2H-吡咯。
