New Catalyst Developed by CCHF

Chemists have developed another catalyst that can selectively activate a carbon-hydrogen bond, part of an ongoing strategy to revolutionize the field of organic synthesis and open up new chemical space.

The journal Nature is publishing the work by chemists at Emory University, following on their development of a similar catalyst last year. Both of the catalysts are able to selectively functionalize the unreactive carbon-hydrogen (C-H) bonds of an alkane without using a directing group, while also maintaining virtually full control of site selectivity and the three-dimensional shape of the molecules produced.

New Research from the Lynn Group on How Protein Misfolding May Kickstart Chemical Evolution

Exciting new research from the Lynn Group is featured in this week’s eScience Commons blog:

Alzheimer’s disease, and other neurodegenerative conditions involving abnormal folding of proteins, may help explain the emergence of life – and how to create it.

Researchers at Emory University and Georgia Tech demonstrated this connection in two new papers published by Nature Chemistry: “Design of multi-phase dynamic chemical networks” and “Catalytic diversity in self-propagating peptide assemblies.”

“In the first paper we showed that you can create tension between a chemical and physical system to give rise to more complex systems. And in the second paper, we showed that these complex systems can have remarkable and unexpected functions,” says David Lynn, a systems chemist in Emory’s Department of Chemistry who led the research. “The work was inspired by our current understanding of Darwinian selection of protein misfolding in neurodegenerative diseases.”

The Lynn lab is exploring ways to potentially control and direct the processes of these proteins – known as prions – adding to knowledge that might one day help to prevent disease, as well as open new realms of synthetic biology.

Emory’s eScienceCommons blog, “Chemists map cascade of reactions for producing atmosphere’s ‘detergent’,” features findings from Joel Bowman‘s recent Nature Chemistry paper.

“We’ve solved another piece of the puzzle in the formation of hydroxyl radicals, by zooming in to see all the steps of the reaction in much finer detail than ever before,” says co-author Joel Bowman, a theoretical chemist at Emory. “This kind of detailed data is important to atmospheric chemists trying to make predictive models for how the atmosphere will respond to climate change.”
