Abstract
-alkylation of 2-pyridones by TfOH-catalyzed carbenoid insertion. In the catalytic system, alkylation of 2-pyridone was achieved with unprecedented regioselectiviy (>99 : 1). This protocol is characterized by mild reaction conditions, metal-free, and simplicity. Moreover, this method provides the desired products in good yield and demonstrates a broad substrate scope in this transformation.
