A novel one-pot thermal cycloaddition of two indenones followed by a decarbonylation and dehydrogenation cascade afforded benzo[c]fluorenones regioselectively. Various substituted indenone derivatives were converted into their corresponding benzo[c]fluorenones in good to excellent yields.
新颖的一锅法将两个茚满进行热环加成,然后进行脱羰和脱氢级联反应,从而选择性地提供了苯并[ c ]芴酮。各种取代的茚满酮衍生物均以良好或优异的产率转化为相应的苯并[ c ]芴酮。
