Taming the carboxyl group for directed carbometalation: Observations on the use of anions, dianions and ester enolates

Carboxylate anions, dianions and ester enolates provide simultaneous protection and activation for directed carbometalation reactions. Advantage can be taken of the bis-carbanionic character of the intermediate for further controlled C-C bond forming reac

Palladium(0)-Catalyzed Alkoxycarbonylation of Allyl Phosphates and Acetates

Palladium-catalyzed alkoxycarbonylation of allyl phosphates under CO (1 atm) at 50 deg C proceeds highly efficiently to give the corresponding β,γ-unsaturated esters.The carbonylation of geranyl phosphate ((E)-11) under CO (1 atm) at 50 deg C gave ethyl ester of homogeranic acid ((E)-12) stereoselectively.The carbonylation takes place at least substituted allylic positions with inversion of configuration.Typically, the methoxycarbonylation of cis-5-(methoxycarbonyl)-2-cyclohexen-1-yl phosphate (cis-16) gave trans-dimethyl-2-cyclohexene-1,5-dicarboxylate (trans-17) selectively.Alkoxycarbonylation of allyl acetates is performed for the first time in the presence of a catalytic amount of bromide ion.The reaction can be rationalized by assuming the mechanism which involves oxidative addition of palladium(0) species to allyl acetates to give ?-allylpalladium acetate, fast ligand exchange of the acetate with bromide, insertion of carbon monoxide to give acylpalladium species, and alkoxylation.
