Palladium-Catalyzed Intramolecular Oxidative Heck Cyclization and Its Application toward a Synthesis of (±)-β-Cuparenone Derivatives Supported by Computational Studies
oxidative cyclization of substituted homoallylic alcohols to form cyclic keto compounds under palladium-catalyzed conditions is described. The reaction has practical applications in the synthesis of sesquiterpenes. The mechanism of cyclization, the key step in the tandemreaction, was analyzed by using density functional theory calculations. A novel and efficient intramolecular oxidative cyclization of substituted
