The olefin insertion step is found to determine both the regioselectivity and chemoselectivity, leading to the tail-to-tail heterohydroalkenylation product. With a small NHC ligand ...

The MCTPs can proceed efficiently under mild conditions near room temperature to afford sulfur-rich polymers with high molecular weight, high yield, high regioselectivity, and good stereoselectivity.

Researchers in China have developed a machine learning tool that can predict both the stereoselectivity and activity of engineered enzymes by analysing their amino acid sequence. They claim their tool ...

2023). Chemical synthesis provides extensive control over the final HMO product, allowing for manipulation of its structure, bond configuration (α or β), regioselectivity (the position of glycosidic ...
