| Outline of Final Research Achievements |
Collaboration between oxygen-linked alkynyl group and transition-metal catalysts was found to utilize the straightforward activation of stable carbon-hydrogen bonds in alkynyl-containing organic substrates. This methods were applicable to the activation
of arylic, vinylic, and benzylic carbon-hydrogen bonds followed by intramolecular annulation or intermolecular annulation with other unsaturated bonded compounds via an insertion of the oxygen-bonded alkynyl group. These transformations led to various oxacycles. In addition, we obtained the information about reaction mechanisms, which give us hints to use normal alkynyl groups for carbon-hydrogen bond activation with transition-metal catalysts.
