title: A facile approach to spirocyclic 2-azido indolines via azidation of indoles with ceric ammonium nitrate.
abstract: This paper describes azidation of indoles with NaN3 and ceric ammonium nitrate (CAN), giving a variety of spirocyclic 2-azido indolines in good yields and moderate diastereoselectivities.
