Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Nature's first green is gold</bold> The cover picture shows the gold(I)‐catalyzed cycloisomerization of O‐tethered 1, 6‐enynes, which proceeds via fused tricyclic compounds with a dihydropyran moiety. As described in their Communication on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">p. 1096 ff., </ext-link> L. Fensterbank et al. continue this ring‐expansion with a two‐step sequence for the transformation of the cyclized compounds into valuable ketomacrolactones, with a motif that echoes natural products. And all this in the golden surroundings of Paris!<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1zt57p0v" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
