title: Rhodium-catalyzed decarboxylative and dehydrogenative coupling of maleic acids with alkynes and alkenes.
abstract: The dehydrogenative coupling of maleic acids with alkynes proceeds smoothly accompanied by decarboxylation under rhodium catalysis to produce variously substituted α-pyrone derivatives. The catalyst system is also applicable to the coupling with 1,3-diynes and alkenes.
