Electrochemical Reactions of Dihydroazaazulanones Possessing a Spirocyclic Moiety: Ring Cleavages of the Spiro-rings, Hydrogen Migrations and Formations of Azaazulanones
摘要:
Electrochemical oxidations of dihydroazaazulanones possessing a spirocyclic moiety afforded two types of dihydroaza-azulonones and one type of azaazulanones. The reaction is considered to proceed via a ring cleavage of the spiro-three membered ring followed by a hydrogen migration.
