Abstract
Abstract 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 rearrangement could be suppressed in the presence of phenol, which allowed the synthesis of 4, 9-dimethoxy-2-methyl-11H- ...
