The ability to construct a peptide or protein in a spatio-specific manner is of great interest for
therapeutic and biochemical research. However, the various functional groups present in …

Abstract [n] Helicenes are polycyclic aromatic molecules in which n ortho‐condensed
benzene or other aromatic rings give rise to helical chiral and highly conjugated structures …

Highly valuable bioconjugated molecules must be synthesized through efficient,
chemoselective chemical modifications of peptides and proteins. Herein, we report the …

The direct and selective conversion of a C–H bond into a C–Se bond remains a significant
challenge, which is even more intricate with substrates having an innate regioselectivity …

A mild and efficient method for preparation of 3-sulfenyl and 3-selenyl coumarins and
quinolinones mediated by artificial light or sunlight is presented. The elaborated protocol …

Organochalcogen-containing cyclic molecules have shown several promising
pharmacological properties. Consequently, different strategies have been developed for …

Cu (II)-mediated C–H sulphenylation or selenylation of Trp indole by a derivative of cysteine
or selenocysteine enables access to the tryptathionine unit or its selenium congener. The …

Glycosylation of bioactive molecules has been found to improve the pharmacokinetic
properties of the parent molecule. However, their syntheses often require tedious protecting …

In recent years, researchers have been exploring the potential of incorporating selenium into
peptides, as this element possesses unique properties that can enhance the reactivity of …

Herein, we report the first examples of N-polyaromatic compounds bearing up to 13 fused
aromatic rings, including 23H-benzo [12, 1] tetrapheno [8, 9-b] benzo [12, 1] tetrapheno [9, 8 …
