A Lewis acid promoted intramolecular Schmidt reaction of N-acylbenzotriazoles with alkyl azides was designed and realized. The benzotriazole was not only employed as an efficient activator for initiating the Schmidt rearrangement but also used as a p

Statement of problem The presence of an anterior loop (AL), accessory mental foramen (AMF), or lateral lingual foramen (LLF) adds complexity to the mental foraminal region, and consequently, implant placement in this region can damage the nerves and

Rh-catalyzed intramolecular condensation of the benzyl azides with α-aryldiazoesters was explored. The reaction proceeded through the nucleophilic attack of the organic azide onto a rhodium carbenoid, while releasing nitrogen gas, affording the α-i
