Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Total Syntheses of Agelamadin F and (±)‐Tauroacidin A, Enabled by NaClO2‐Mediated Coupling Reactions of Oroidin and Amines

Chemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
Total syntheses of agelamadin F and (±)‐tauroacidin A were achieved by sodium chlorite (NaClO2)‐mediated oxidative C─N coupling. Nine C15–N–amino acid‐substituted oroidin derivatives were successfully prepared to demonstrate the applicability and versatility of this oxidative coupling reaction.
