The Effect of the Gem‐Dimethyl Unit in the Gold‐Catalyzed Cycloisomerization of Aliphatic 1‐Bromoalkynes

European Journal of Organic Chemistry, Volume 29, Issue 12, 23 March 2026.
The conformational effect of the gem‐dimethyl motif and its isostere cyclopropane unit in the gold‐catalyzed cycloisomerization of aliphatic 1‐bromoalkynes has been studied. An unexpected inhibitory effect of the cyclopropane ring has been observed.

Fluorinated Glycan Frameshifts: Automated Synthesis Expedites the Study of Glycan‐Protein Interactions by 19F‐BioNMR

Angewandte Chemie, Volume 138, Issue 12, 16 March 2026.
Given the prominence of 19F‐bioNMR in structural research, fluorinated glycans hold enormous potential in glycomimetic frameshift design. However, challenges associated with the stereocontrolled synthesis of these disruptive actors continue to frustrate advances. To address this, the automated synthesis of selectively C‐2 fluorinated glycans related to

Visible‐Light Mediated Functionalization in Phe‐Containing Peptides Upon a Debenzylative Amination Process

Advanced Synthesis &Catalysis, Volume 368, Issue 6, 17 March 2026.
Selective late‐stage modification of N‐terminal phenylalanine short peptides is achived by visible‐light initiated reaction with N‐iodoimides in a debenzylation–amination process. This metal‐free method permits the incorporation of N‐containing heterocycles into the α‐position of the peptide backbone.

Synthesis of Niraparib via Chemoenzymatic Dearomatization of Substituted Pyridines

Advanced Synthesis &Catalysis, Volume 368, Issue 6, 17 March 2026.
The synthesis of the PARP inhibitor Niraparib has been achieved via a chemoenzymatic dearomatization strategy. Chemical reduction combined with a one‐pot enzymatic cascade comprising an amine oxidase (AmOx) and an ene imine reductase (EneIRED) allowed for asymmetric reduction with high enantioselectivity.
