| Outline of Final Research Achievements |
This research project focused on development of new synthetic strategy and tactics focusing on intra-molecular redox transformations. Three research topics are addressed. At first, retro-[4+2] cycloaddition reaction for enolsilyl ether of dioxinone derivative was studied. The planned reaction proved feasible by heating of the substrate in toluene or xylene, giving the corresponding allene derivatives in moderate to high yield. In second, reaction of allenes and nitrones were studied. Upon heating of the allenes with nitrones underwent unusual homolytic N-O bond cleavage followed by recombination of resulting radicals to form a C-C bond, affording the corresponding lactams albeit in low yields. This research has been also studied intramolecular redox reaction of naphthoquinone derivatives, enabling construction of a new heterocyclic ring, typically furan ring skeletons. This method would serve as an efficient way to synthesize various polycyclic compounds.
