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

Decarboxylative Csp3–N coupling reactions have been developed through electrochemicaloxidation of amino acids. The reaction proceeds via anodic oxidative decarboxylation of carboxylic acids to form stabilized carbocations, which are trapped by azoles or amides to construct C–N bonds. This method avoids the preactivation of carboxylic acids and the use of expensive transition-metals and external chemical

Dipolestabilizedcarbanion 2 cyclizes to afford the key intermediate 2-benzotriazolyl-N-Boc-pyrrolidine 3, which undergoes nucleophilic displacement of the benzotriazolyl group to afford various 2-substituted-N-Boc-pyrrolidines in good yields.
