Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Spiraling up the rings</bold> according to K. Kamikawa and co‐workers in their Communication on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 11837 ff.</ext-link>; they report that azahelicenes with a unique helical‐shaped backbone can be efficiently synthesized in high yields by utilizing palladium‐catalyzed CH annulation reactions. Functionalization at the C5 position in azahelicenes by using palladium‐catalyzed CH arylation also gave coupling products in good yields. These two CH bond activation processes can also be performed in one pot.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg36r4bk9s" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
