Smooth isoindolinone formation from isopropyl carbamates via bischler-napieralski-type cyclization

Adachi, Satoshi,Onozuka, Masao,Yoshida, Yuko,Ide, Mitsuaki,Saikawa, Yoko,Nakata, Masaya

, p. 358 - 361 (2014/04/03)

Isopropyl carbamates derived from benzylamines provide isoindolinones by treatment with phosphorus pentoxide at room temperature. Utility of this Bischler-Napieralski-type cyclization and a new mechanism involving a carbamoyl cation for rationalization of this smooth conversion are discussed.
