We report the first examples of catalytic, intramolecular N-heterocycle arylation by nucleophilic aromatic substitution (SNAr), a general method for synthesis of highly strained macrocycles and medium-sized heterobiaryl atropisomeric rings. Key to the approach is the ability to generate a strong base catalytically, as...

Hydridic hydrogen atoms, where hydrogen carries increased electron density, form a distinct class of noncovalent interactions, yet their structural and energetic characteristics remain poorly understood. Shallow multi-minima potential-energy surfaces and competing low-energy docking motifs make conventional NMR insuffi...

We evaluated a fully machine-learning-assisted workflow for NMR crystallography by combining the Universal Model for Atoms (UMA) interatomic potential for crystal structure optimization with the ShiftML3 prediction of solid-state NMR shieldings. Benchmarking against conventional periodic density functional theory (DFT)...

Accurately predicting NMR chemical shifts of exchangeable protons in solution remains challenging because of the combined influence of solute–solvent interactions and molecular dynamics. We introduce a framework that integrates machine-learning molecular dynamics (ML-MD) with the ShiftML3 machine-learning shielding mod...
