Data-Efficient, Chemistry-Aware Machine Learning Predictions of Diels–Alder Reaction Outcomes [PDF]
The application of machine learning models to the prediction of reaction outcomes currently needs large and/or highly featurized datasets. We show that a chemistry-aware model, NERF, which mimics the bonding changes that occur during reactions, allows ...

Fluorogenic Sydnones for Bioorthogonal Labeling of DNA
Chemistry – A European Journal, EarlyView.Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.

A Unified Approach for the Synthesis of Conformationally Locked and sp2‐sp3 Fused Hybrids
Chemistry – A European Journal, EarlyView.This study presents a systematic platform to build rigid sp2–sp3 hybrids via benzyne cycloadditions. Arene‑fused bicyclic oxa‐, aza‐, and carbocycles are converted into medicinally relevant amino acids and applied to Enalapril analogues synthesis. The hybrids combine aromatic interactions with 3D rigidity, tuning lipophilicity, pKa, and solubility ...
