Addition of aryl substituents to cyclohexadienyliron electrophiles in the development of routes to C12 central building blocks for alkaloid synthesis
摘要:
Novel iron-aroyl complexes or synthetically prized arylcyclohexadienyl complexes can be formed from tricarbonyl(eta(5)-1,4-dimethoxycyclohexadienyl)iron(1 +) hexafluorophosphate(1 -) by correct control of reaction sequences that exploit the addition of aryllithium reagents to introduce the aromatic group. Bimetallic products are obtained when a tricarbonylchromium-bound aryllithium reagent or the corresponding cuprate are employed. (C) 1999 Elsevier Science S.A. All rights reserved.
