Helical Dinaphthothiophenes Reveal the Limits of BN‐Based Optical Tuning

European Journal of Organic Chemistry, EarlyView.
A BN‐7‐thia[5]helicene and an analogous CC‐7‐thia[5]helicene were prepared in two efficient synthetic routes. Their geometrical structures barely differ, which allows us to judge the influence of the BN substitution on the electronic properties. The formal substitution of carbon–carbon (CC) units by boron–nitrogen (BN) units is an established strategy ...

Click Bioconjugation of Aza‐BODIPY Fluorophores to LfcinB Peptides for Improved Biocompatibility

European Journal of Organic Chemistry, EarlyView.
Click bioconjugation attaches NIR aza‐BODIPY fluorophores to LfcinB‐derived anticancer peptides via CuAAC and thiol‐maleimide chemistry. Conjugates exhibit improved predicted solubility while retaining strong NIR absorption (703–730 nm). Peptide‐aza‐BODIPY conjugates induce apoptotic morphology in HeLa cancer cells.

Gold‐Catalyzed Cyclization of Indole‐Tethered Alkynes Enabling Synthesis of Exocyclic Alkenyl Tetrahydrocarbazoles

European Journal of Organic Chemistry, EarlyView.
An efficient gold‐catalyzed intramolecular cyclization of indole‐tethered alkynes using AgNTf2 as an additive has been developed, which provides bioactive exocyclic alkenyl tetrahydrocarbazoles with up to 85% yield. Control experiments and DFT studies indicate that the reaction proceeds via a 6‐exo‐dig cyclization pathway, with gold acetylide complexes

Axial Chirality Control Through Palladium‐Catalyzed Alkenylation Reactions for the Atroposelective Synthesis of 4‐Arylquinolin‐2‐ones

European Journal of Organic Chemistry, EarlyView.
Palladium(II)‐catalyzed intramolecular C─H alkenylation of cinnamides allows the atroposelective synthesis of axially chiral 4‐arylquinolones, with the chirality being installed by ring formation. DFT studies have shown that the reaction proceeds by prior activation of the alkene and the enantioselectivity is determined during the β‐hydride elimination
