Synthesis of the Benzo[b]fluorene Core of the Kinamycins by Arylalkyne-Allene and Arylalkyne-Alkyne Cycloadditions

Arylalkyne–allene and arylalkyne–alkyne cycloadditions yields benzo[a]fluorenones, which are related to the tetracyclic core of the kinamycins. In the arylalkyne–alkyne cycloadditions, we found a rearrangement that produces benzo[a]fluorenones, in addition to the expected benzo[b]fluorenones. This r...
