Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Gold (homepage: http://www.hashmi.de) carbenes generated <italic>via</italic> 1, 2‐migration of a propargylic ester group can be transferred over a tethered alkyne. The use of aromatic backbones leads after a 1, 7‐carbene transfer to a benzyl‐stabilized carbene as intermediate. A 1, 2‐shift of a methyl group delivers vinyl‐substituted β‐naphthol derivatives as the final products.</p> <p> <boxed-text content-type="graphic" position="anchor" orientation="portrait"> <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg3h7zqt84" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /> </boxed-text> </p> </abstract>
