| Outline of Final Research Achievements |
Taking into account the feature of the orthogonal π component of allene, which is an integrated double bond, investigation was conducted for the purpose of constructing a new reactivity by a cyclization reaction with a multiple bond component using a rhodium catalyst. As a result, by using an alkyne-allene-alkyne compound etc., a plurality of new other steps progressing through oxidative cyclization and reductive elimination proceed, and a method for obtaining a corresponding polycyclic skeleton was found. It should be noted that cyclization proceeded with activation of the inactive C―C bond without ring strain adjacent to the alkyne.
