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

Recurrence of low-grade appendiceal pseudomyxoma peritonei (PMP) with splenic invasion and parastomal hernia is exceptionally rare. We present a 47-year-old female with recurrent PMP, four years post-cytoreductive surgery (CRS) and hyperthermic intra

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

A rhodium-catalyzed diastereo- and enantio-selective cyclopropanation of α-boryl styrenes with α-diazoarylacetates was established. Rh2(S-PTTL)4 (0.2 mol%) was found to be effective for the conversion, and 21 diastereopure cyclopropylboronates were

A designed Tf2O-promoted intramolecular Schmidt reaction of 2-substituted ω-azido carboxylic acids was demonstrated. Tf2O was used as an activation reagent for the carboxylic acid, and ω-azido anhydride was in situ generated, releasing a molecular
