available N-chlorosulfonyl carbamate as an effective amidyl-radical precursor, which could be readily prepared from commercial low-cost chlorosulfonyl isocyanate (CSI) and alcohol feedstocks. The synthetic potency of this developed protocol was well demonstrated by direct amidation of various quinoxalin-2(1H)-ones. The protocol could be further streamlined by implementing a one-pot/two-step/three-component
本文报道了一种新的光诱导酰胺化方案的设计和开发,该方案使用容易获得的N-氯磺酰氨基甲酸酯作为有效的酰胺自由基前体,该前体可以很容易地由商业低成本氯磺酰异氰酸酯(CSI)和醇原料制备。该开发方案的合成效力通过各种喹喔啉-2(1 H )-酮的直接酰胺化得到了很好的证明。通过实施CSI、酒精和喹喔啉-2(1 H )-一的一锅/两步/三组分工艺,可以进一步简化该方案,并显着提高反应效率。该方法为快速扩展含氮分子复杂性提供了一个有趣的机会,从而激发了对CSI试剂新反应模式的全面探索。
