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.

Nuclear Quantum Effects on the Organic Bifurcation Reaction in Microsolvated Water Clusters: Ring‐Polymer Molecular Dynamics Calculations Using an Explicit Solvation Model

Journal of Computational Chemistry, Volume 47, Issue 19, 15 July 2026.
Ring‐polymer molecular dynamics in explicit water clusters shows that nuclear quantum effects steer an organic bifurcation reaction—enhancing the minor (4 + 2) channel and accelerating water‐mediated proton transfer—proving that accurate aqueous reaction dynamics require both explicit solvation and nuclear quantum effects. ABSTRACT Solvent environments

Reaction Enumeration Based on NBO‐Informed Molecular Graphs

Journal of Computational Chemistry, Volume 47, Issue 19, 15 July 2026.
NBO‐informed molecular graphs represent chemistry via valence orbitals rather than atomic connectivity, enabling consistent reaction analysis across environments. By identifying delocalized motifs and increasing complexity adaptively, the framework enables efficient exploration of inaccessible mechanisms and diverse catalytic and reaction networks for ...
