The carbanions of Horner reagents (α-cyanated and α-acylated phosphonic esters 2, 8 and 11) are amidoethylated with activated aziridines 1a-e. Twofold amidoethylation is observed with the phosphononitrile 2 only. The primary products 9 formed from the phosphono acetate 8 tend to cyclize yielding phosphonopyrrolidinones 10.
Horner试剂的碳负离子(α-氰化和α-酰基化磷酸酯2、8和11)与活化的氮杂环丙烯1a-e发生胺基乙基化反应。只有磷酸氰化物2观察到双重胺基乙基化。由磷酸醋酸酯8生成的主要产物9趋向于环化,形成磷酸吡咯烷酮10。
