The copper(I) or ruthenium(II)-mediated radical cyclisation of halo-amides has been utilised to afford functionalised pyrrolidinones via 5-endo-trig or 5-exo-trig radical cyclisation pathways. This methodology has been applied to novel and concise syntheses of the anti-epileptic drug gabapentin and the biologically active natural product pulchellalactam.
铜(I)或钌(II)介导的卤代酰胺的自由基环化已被使用,以便通过5-,得到官能化的吡咯烷酮内切-三角函数或5-外型- trig的自由基环化通路。该方法已应用于抗癫痫药加巴喷丁和生物活性天然产物普氏内酰胺的新颖,简洁的合成中。
