Abstract: 
This account describes synthetic approaches for curved polycyclic aromatics such as circulenes, helicenes and cycloparaphenylenes, relying on a [2+2+2] cycloaddition. A common feature of all these structures is that their synthesis needs to deviate benzene rings from planarity. Relying on [2+2+2] cycloaddition reactions for this task leads to impressive, and in parts, surprising results. The examples shown here and their optimized reaction conditions contribute to a better understanding of processes going on during the reaction. This knowledge is expected to lead to new designs of challenging syntheses using the [2+2+2] cycloaddition methodology.1 No Gain, No Strain: Synthesis of Curved Aromatics2 Examples for the Preparation of Strained Systems Relying on a [2+2+2] Cycloaddition2.1 Circulenes2.2 Helicenes2.3 Cycloparaphenylenes3 Conclusion and Outlook
