Generative and Experimental Validation of High Refractive Index Polymers via Domain Knowledge Approach with Small Data

Advanced Intelligent Discovery, EarlyView.
This research demonstrates that the combination of domain knowledge–based multiple regression, multi‐objective Bayesian optimization, and generative models is a suitable prediction tool for candidates of high refractive index polymers, even with the constraints in the model trained on limited data. The experimental validation can reproduce the proposed

Synthesis, Cytostatic and Antibacterial Evaluations of N-4-benzoylcytosine–1, 2, 3-triazole and 7-deazapurine–1, 2, 3-triazole Hybrides

, 2017
Cytosine and 7-deazapurine (pyrrolo[2, 3-d]pyrimidine) derivatives have a great role in medicinal chemistry and have shown rather marked antitumor, antiviral, antibacterial and antiinflammatory activities.[1-4] 7-deazapurines are an important class of compounds, structurally and chemically related to naturally nucleosides.

A Mild Disilane‐Enabled Halide‐to‐Deuterium Manifold With D2O for Aryl and Benzylic Halides

Angewandte Chemie, EarlyView.
A broadly applicable Pd‐catalyzed dehalogenative deuteration enables efficient conversion of aryl and benzylic halides with inexpensive deuterium oxide (D2O). The method proceeds under exceptionally mild conditions without strong bases, harsh reductants, or stoichiometric Lewis acid halide scavengers, and tolerates a wide range of functional groups ...
