Intramolecular Addition of Stabilized Enolates to (η6-Arene)ruthenium Complexes: Synthesis of Ru-Coordinated Azaspirocycles
摘要:
[GRAPHICS]Stabilized enolates attached to, cationic (arene)(RuCp)-Cp-II complexes via an amide linkage were found to participate in nucleophilic aromatic addition reactions resulting in the formation of novel cyclohexadienyl-Ru azaspirocycles. Enolate addition to the activated arene ring was found to proceed with complete stereoselectivity.
