The Widenhoefer group has recently reported the gold(I)-catalyzed stereoconvergent, intermolecular enantioselective hydroamination of chiral, racemic 1,3-disubstituted allenes, which represents the first example of enantioselective intermolecular allene hydroamination. The method effectively forms N-allylic carbamates, which are important chiral building blocks, with high regio- and diastereoselectivity and with up to 92% ee. The editors of Angewandte Chemie have designated it a “hot paper”. Butler, K. L.; Tragni, M.; Widenhoefer, R.Read More
How do ionic interactions and macromolecules play a role in iron transport in living cells? Find out by reading the chapter from the Crumbliss lab “Iron Transport in Living Cells” by A. L. Crumbliss and C. J. Parker Siburt, which was featured on the cover of the monograph Ionic Interactions in Natural and Synthetic Macromolecules (Wiley, 2012), edited by Visiting Professor of Chemistry Alberto Ciferri and Angelo Perico.Read More
Graduate student Nick Polizzi and collaborators in Beratan's lab have built a theoretical model to describe how charge flows through bacterial appendages, known as pili. Pili are implicated in the exchange of electrons between living organisms and inorganic substrates. These studies may assist in the design of future semi-biological solar cells that would convert sunlight into liquid fuels, with the help of photovoltaics that are "plugged" into living bacteria.Read More
Recent work from the Craig lab reports a functional group that grows longer in response to applied machincal forces, a response that can subsequently be reversed by shining light on the sample. Read more about the new mechanophore and its properties here.
