Diels–Alder and Friedel–Crafts-Type Reactionsin Friedel–Crafts-type reaction: (1) polar unsaturated bonds should be well designed and incorporated into the substrates; (2) it is better to introduce the directing or blocking groups to promote the regioselectivity.

Metal-Mediated Reactions+2+2] cycloisomerization method. Moreover, other types of metal-mediated reactions are also utilized for the preparation of helicenes, such as Pd-catalyzed twofold Stille cross-coupling reaction, Pd-catalyzed double Suzuki-Miyaura cross-coupling, Ti-mediated McMurry coupling, intramolecular palladiu

Asymmetric Synthesiscentral chirality or axial chirality is accepted as an efficient and practical method to construct helicenes, especially the long ones. In these strategies, transition metal-mediated reactions, especially the cycloisomerization, Diels-Alder addition, and chiral auxiliary-induced reactions ar
