An operationally simple method to employ nonactivated carboxylic acids as alkylating agents in the N-alkylation of heterocycles is reported through an electrochemically driven anodic decarboxylative process. A wide substrate scope across a range of heterocycles is demonstrated along with a series of applications that significantly reduce the step count required to access such medicinally relevant structures

A dehydroxylative Csp3-N coupling reaction assisted by triphenylphosphine has been developed through electrochemicaloxidation. The reaction proceeds via anodic oxidation of triphenylphosphine to generate its corresponding radical cation, followed by reacting with hydroxyl groups to form alkoxy triphenylphosphonium ions, which are trapped by azoles or amides to construct C-N bonds. This method provides
