Direct access to the polyfluorinated lactams through Ca(NTf2)2 catalyzed by either the reductive amination of biomass-derived keto acids with amines or the reductive amination of amino acids with carbonyl derivatives under solvent-free conditions is realized. The two versatile protocols display chemospecificity and good substrate tolerance to deliver five- to eight-membered lactams with diverse functionality

生物的还原胺化催化直接获得多
氟内酰胺。这两种通用方案显示出
化学特异性和良好的底物耐受性,可提供具有不同功能和取代模式的五至八元内酰胺。随后在药物分子后期功能化中的应用进一步证明了该方法的稳健性。
