Popis: | An interceptive decarboxylative allylation protocol has been developed utilizing pyrone as a C4 synthon. This palladium-catalyzed transformation difunctionalizes the pyrone moiety by in situ generation and activation of both the electrophile and nucleophile via a double decarboxylation pathway. Ultimately, allyl carbonates react smoothly with 2-carboxypyrone under mild reaction conditions to generate synthetically useful acyclic dienoic esters, forming carbon dioxide as the sole byproduct. |
