Herein we have reported the palladium(0)catalyzed decarboxylative oxa-Michael addition/remote α-allylation/1,3-migration of prochiral allyl carbonate-tethered cyclohexadienones in good yields. This unconventional intramolecular rearrangement is triggered by the base-mediated retro-Michael ring-opening reaction (β-elimination) and subsequent syn-selective oxa-Michael addition on the less substituted enone functionality. The generality of tandem decarboxylative allylation was examined with various substrates and in the gram-scale reaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
