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 …

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 …

A facile synthetic route to dimethylsila [7] helicene by using a Lewis acid catalyzed double-
cyclization reaction for construction of the twisted two phenanthrene moieties is described …

An original approach to helicene frameworks exploiting atom economic isomerization of
appropriate energy-rich aromatic cis, cis-dienetriynes has been developed. The new …

A convergent approach based on Diels–Alder reactions between polycyclic dienes and
benzoquinones has emerged as a powerful tool for the construction of helicenequinones …

The versatility of the trityl cation (TrBF4) as a highly efficient Lewis acid organocatalyst is
demonstrated in a light induced benzylic brominaion of alkyl‐arenes under mild conditions …

The unique structure of helicenes1 makes them excellent candidates as new materials and
chiral auxiliaries in asymmetric synthesis. 2 The potential use of such species depends on …

The synthesis of enantiopure C‐12 methoxy‐or alkyl‐substituted 5, 7, 8, 12b‐tetrahydro [4]
helicene quinones 16 and 17 and the 7, 8‐dihydroaromatic analogues 4 and 5 has been …

Abstract The reaction of 1, 4‐divinyl‐1, 3‐cyclohexadiene, 5, 8‐dimethoxy‐or tert‐
