描述.This book systematically reviews recent advances in the synthetic methods and applications of helicenes. The first part of this book introduces the nomenclature and structural features of helicenes. The second part reviews several classic and useful methods as well as recently-developed approaches for the preparation and functionalization of helicenes, including photocyclization and Diels-Alder reactions, which are two important breakthroughs in the syntheses of helicenes. In the last part, the applications of helicenes in asymmetric syntheses, molecular machines, molecular recognition, self-assembly and other fields are discussed. This book provides a useful reference source for researchers and graduate students working not only in the area of helicene chemistry, but also in other research areas including materials science, supramolecular chemistry, coordination chemistry, and physical organic chemistry...Chuan-Feng Chen is a Professor at the Institute of Chemistry, Chinese Academy of Sciences, China..

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 [2+2+2] cycloisomerization, Diels-Alder addition, and chiral auxiliary-induced reactions ar
