title: Gold-catalyzed oxidative cyclization of 4-allenyl-1-ynes with 8-methylquinoline oxide.
abstract: Gold-catalyzed oxidative cyclizations of 4-allenyl-1-ynes with 8-methylquinoline oxide are described; diverse products are produced depending on the allenyl substituents. This reaction comprises initial formation of α-oxo gold carbenes that are attacked by allene to form allyl cation intermediates.
