Abstract Successive transformations including oxidation of 1, 4-dihydronaphthalene into 1, 2, 3, 4-tetrahydronaphthalen-2-one, Reformatskii reaction of the latter with methyl bromoacetate, ozonolysis of the Reformatsky reaction product, and Emmons olefination of the aldehyde group in methyl 3-oxo-5-(2-formylphenyl) pentanate thus formed gave analogs of highly active dienoate juvenoids having an aromatic ring in their molecules.
