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 …

Although chiral mechanically interlocked molecules (MIMs) have been synthesised and
studied, enantiopure examples are relatively under-represented in the pantheon of reported …

A chiral phosphine oxide-ligated Ni–Al bimetallic catalyst was used to realize an
enantioselective C2–H alkylation of pyridines without the need of a C2-block. A wide range …

Conspectus Advanced molecular nanocarbons are now in the spotlight reflecting the basic
discoveries of fullerenes, carbon nanotubes, and graphene. This research area includes …

The cation− π interaction is an attractive noncovalent interaction between a cation and a π
system. Due to the stronger interaction energy than those of the other π interactions, such as …

Rotaxanes are interlocked molecules in which a molecular ring is trapped on a dumbbell-
shaped axle because of its inability to escape over the bulky end groups, resulting in a so …

Can green chemistry be the right reading key to let organocatalyst design take a step
forward towards sustainable catalysis? What if the intriguing chemistry promoted by more …

We designed bifunctional 4-pyrrolidinopyridines as powerful Lewis base catalysts. The
catalyst structure features a 4-hydroxy-2-(hydroxydiphenylmethyl) pyrrolidine-1-formyl group …

We have developed an efficient modular asymmetric synthesis of azahelicenes through an
organocatalyzed asymmetric multicomponent reaction from readily available polycyclic …

This literature overview demonstrates that helically chiral ligands and organocatalysts have
been largely neglected so far. However, a few recent studies on helical pyridine, the …
