Iron-catalyzed cross-aldol reactions of ortho-diketones and methyl ketones.
Iron-catalyzed cross-aldol reactions of ortho-diketones and methyl ketones were developed and the thus formed aldol products were efficiently transformed into cyclohepta-2,4,6-trienone derivatives (tropones) under thermal conditions via ring-expansion.
