A KSO/TEMPO-induced oxidative cyclization of N-unprotected enaminoesters and enaminones that gave 1 H-pyrrol-2(3 H)-ones in good yields with broad functional group compatibility is reported. This method provides easy access to 1,2-carbon migration of ester or acyl group under transition-metal-free conditions.
本文报道了 KSO/TEMPO 诱导的 N-未保护的烯胺酯和烯胺的氧化环化反应,该反应以良好的收率和广泛的官能团兼容性得到了 1 H-吡咯-2(3 H)-酮。该方法在无过渡金属条件下提供了酯基或酰基 1,2-迁移的简便途径。
