We report a direct azidation of benzylic C(sp3)−H bonds via an electrochemical process, which use cheap and durable graphite plates as electrodes, without any external oxidants or metal catalysts. This protocol is a novel, green and environmentally benign synthetic strategy to achieve azidation of C(sp3)−H in benzylic group. More importantly, these azidation products are suitable for late‐stage functionalization to afford diversified triazole and tetrazole derivatives. [ABSTRACT FROM AUTHOR]

A facile method for the synthesis of indanones was developed under metal- and additive-free conditions, wherein L -proline served as an efficient and environmentally benign catalyst. Compared with previously synthesized indanones, synthesis by the transition-metal-catalyzed intramolecular hydroacylation of 2-vinylbenzaldehyde provided a more green synthetic pathway to indanone scaffolds with good to excellent yields. More importantly, it could be used to synthsize the anti-AD drug donepezil. [ABSTRACT FROM AUTHOR]
