title: Efficient synthesis of bibutenolide derivatives through oxidative dimeric cyclization-coupling reaction of 2,3-allenoic acids.
abstract: An oxidative coupling-dimerization reaction of 2,3-allenoic acids was observed to provide an efficient route to bibutenolide derivatives, which are not readily available. A new system (PdCl(2)/RI/air) for regeneration of the palladium(II) catalyst was also established. [reaction: see text]
