This paper describes a highly enantioselective epoxidation of α,β-unsaturated esters using the fructose-derived ketone 2 as catalyst and Oxone as oxidant. High ee's have been obtained for a number of ...
Employing chiral organic bases allowed us to realize efficient desymmetrizations using carbon nucleophiles, such as 1,3-dicarbonyl compounds, cyanoacetates, and oxindoles. These reactions, performed ...
Carbon monoxide—that invisible, odorless silent killer—could be a risk in your hotel room. Unfortunately there’s no real way of knowing how protected you are unless you take precautions.
Earth’s atmosphere now has more carbon dioxide in it than it has in millions — and possibly tens of millions — of years, according to data released Thursday by the National Oceanic and ...
