Protecting-Group-Free Solid-Phase Anchoring of Polyphenolic C-Glucosidic Ellagitannins and Synthesis of 1-Alkylamino-Vescalagin Derivatives with Chemspeed’s Fully Automated SYNTHESIZER

September 1, 2014

The C-glucosidic ellagitannins vescalagin and vescalin are among the plant polyphenols that have been shown to interact with protein targets in a specific manner. This work describes a protecting-group-free method to immobilize these protein-binding natural products on a solid support, and a functionalizing cleavage method, which is adaptable to the solution-phase synthesis of vescal(ag)in derivatives, and which advantageously permitted the preparation of 1-alkylamino derivatives of vescalagin.

Stable acidic oxygen-evolving catalyst discovery through mixed accelerations

Ruthenium oxides (RuOx) are promising alternatives to iridium catalysts for the oxygen-evolution reaction in proton-exchange membrane water electrolysis but lack stability in acid. Alloying with other elements can improve stability and performance but enlarges the search space.

Experimental and kinetic study of the microwave-assisted catalytic conversion of glucose

Microwave technology offers rapid, selective, and efficient heating, making it a valuable tool for process intensification. In this context, this study employed microwave energy for rapid reaction optimization and reliable kinetic analysis for the catalytic conversion of glucose. Dehydration (DeH) and retro-aldol condensation (RAC) are two main routes for the catalytic conversion of glucose into valuable platform chemicals such as levulinic acid, methyl lactate, and other byproducts.

Toward fully autonomous closed-loop molecular discovery – A case study on JAK targets

Bridging AI and self-driving laboratories, we introduce the first fully-automated, closed-loop molecular discovery cycle, exemplified by the identification of novel JAK inhibitors. With minimal human intervention, we combined AI-driven molecular design and retrosynthesis with IBM’s synthesis automation system RoboRXN and Arctoris’ Ulysses platform for automated in-vitro screening.
