An AlCl3·MeNO2-mediated Dieckmann cyclization reaction of general synthetic utility enables direct access to complex 2-alkyl-1,3-dione building blocks from readily available dicarboxylic acid and acid chloride substrates. This method enables direct access to the chiloglottone plant pheromones from commercially available starting materials in a single synthetic transformation.
