Not forbidden : Thermal 4 n electron electrocyclic reactions of Hückel topology structures proceed via “allowed” conrotatory pathways. However, for a Möbius topology, the Woodward–Hoffmann rules may be reversed and a “forbidden” disrotatory pathway can be preferred as shown theoretically for dodecahexaene 1 that transforms via a Heilbronner–Möbius aromatic transition structure 2 into a cyclic polyene 3 .
