Ozonolysis of naphthalene in aqueous methanol, followed by the reduction of peroxy compounds thus formed with potassium iodide in the presence of acetic acid, gave 3-methoxy-2-benzofuran-1(3H)-one. In the absence of water, the product was methyl o-formylbenzoate. The latter was used as a synthon for the preparation of aromatic analogs of (2E)-2,6-dimethyloct-2-ene-1,8-diol ethers which are effective juvenoids.

conventional directing template strategies via a covalent binding to the substrates are always hindered by prior stoichiometric installation and removal of the directing groups. Herein, we report a palladium-catalyzed meta-selective C–H olefination of aromatic carbonyl compounds by noncovalent hydrogen-bonding interaction. N,N′-Substituted ureas were engineered to serve as a H-bonding donor for binding
