In this review, we discuss the rich chemistry of helicenes and helicenoids containing main-
group elements. Enantioenriched helicenic derivatives containing main-group elements B …

1. INTRODUCTION Bicyclic oxygen heterocycles resulting from fusion of benzene ring with
5, 6-positions of either 2H-or 4H-pyran ring system are designated as 2H-chromene (2H-1 …

Helicenes are polycyclic aromatic compounds with nonplanar screw-shaped skeletons
formed by ortho-fused benzene or other aromatic rings. 1, 2 The first helicenes 1 and 2 …

The development of a one‐step borylation of 1, 3‐diaryloxybenzenes, yielding novel boron‐
containing polycyclic aromatic compounds, is reported. The resulting boron‐containing …

Carbohelicenes belong to a class of fascinating, chiral, and helicoidal molecules, which
have a rich history in chemistry since the very beginning of the 20th century. A renewed …

Carbohelicenes generally incorporate a helical, distorted, conjugated, polyaromatic system
with ortho-fused benzenoid rings, which is a fundamental molecular characteristic of this …

The coordination and/or organometallic chemistry of π-helicenic ligands is a powerful tool to
generate multifunctional molecules displaying optimized chiroptical properties combined …

Azaboradibenzo [6] helicene, a new semiconductor material possessing helical chirality, has
been synthesized via a tandem bora-Friedel–Crafts-type reaction. Unprecedented carrier …

Helicenes are molecules with ortho-fused aromatic rings that adopt an inherently chiral
helical shape. This helical topology combined with the extended π-conjugated system …

Enantioenriched pyrido [6] helicenes and furan-containing pyrido [7] helicenes have been
synthesized through palladium-catalyzed double imidoylative cyclization by applying axially …
