A FeCl2-catalyzed homocoupling of α,β-unsaturated ketoximes in batch and flow is reported. This protocol demonstrates broad substrate scope and functional group tolerance, providing an alternate route toward the synthesis of 2,4,6-trisubstituted pyrimidines under mild conditions. Also a gram-scale reaction has been performed to evaluate the applicability of this method.
报道了分批和流动的 FeCl 2催化的α,β-不饱和酮肟的同源偶联。该协议展示了广泛的底物范围和官能团耐受性,为在温和条件下合成 2,4,6-三取代嘧啶提供了替代途径。还进行了克级反应以评估该方法的适用性。
