A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.

A spiro Meisenheimer compound

Recueil des Travaux Chimiques des Pays-Bas, 1965
AbstractA Meisenheimer compound has been prepared by the action of a base on 1‐(2′‐hydroxyethoxy)‐2,4,6‐trinitrobenzene. The structure contains a 1,3‐dioxolane ring linked to the six membered ring containing the pentadienate system by a common carbon atom.
