Abstract

<p>Efficient synthetic route to 1,3-dialkynyl- and 1,3-dialkenylisobenzofurans, new π-extended congeners of isobenzofurans, was reported. A three-step protocol including double nucleophilic additions of alkynyllithiums to <i>o</i>-phthalaldehyde and selective oxidation enables us to prepare various functionalized π-extended isobenzofurans. The photophysical properties of these π-extended isobenzofurans are also evaluated.</p>
