A base-mediated aerobic oxidation of the C–H bond adjacent to the N-atom of a secondary amine to form an imine intermediate under mild metal-free basic conditions has been developed. Accordingly, this new strategy has been successfully applied to the synthesis of various di-, tri-, and tetra-substituted α-aminocyclopentenones through a tandem aerobic oxidative [4 + 1] carbocyclization reaction of N-aryl
在温和无
金属的碱性条件下,已开发出一种碱介导的与仲胺N原子相邻的C–H键的好氧氧化,从而形成
亚胺中间体。因此,该新策略已成功地通过N-芳基α'-
氨基-α的串联好氧氧化[4 +1]碳环化反应成功地用于合成各种二,三和四取代的α-
