The degenerate side chain approach to the carbon analog of the Claisen rearrangement. Formation of nine-membered rings by a sterically accelerated ene reaction
Synthesis of functionalized benzannulated compounds
摘要:
Functionalized indane and naphthalene derivatives have been prepared according to two routes involving a nickel-catalyzed electrochemical arylation of activated olefins as the key step. The first method is a cascade process including the intramolecular nucleophilic addition of the first formed enolate intermediate. In the second method the cascade reaction is prevented by in situ protonation of the enolate, and the cyclization is further conducted chemically. This is an overall more efficient method than the first one, based on the electrochemical process. (C) 2008 Elsevier Ltd. All rights reserved.
