Chemists at the University of York, UK, have found an efficient new route for preparing a useful class of organic compounds. Steven Raw and Richard Taylor have developed a simple route to prepare highly-substituted pyridines in a 'one-pot' procedure rather than the more usual four-step 'two-pot' procedure. The process gives good yields and is applicable to the synthesis of a variety of substituted pyridines.
Chemists from the Kyoto Pharmaceutical University in Japan have developed odourless alternatives to thiols and sulfides for the industrially important Corey-Kim and Swern oxidations (conversion of alcohols to aldehydes and ketones). As well as eliminating the unpleasant aroma traditionally associated with these reactions, the odour-free reagents prepared by Kiyoharu Nishide and Manabu Node and colleagues are easily made, relatively cheap and easily retrieved by work-up with water.
Analytical scientists from the universities of Bristol, Keele and Edinburgh, UK, have discovered a way to determine the origin of 'bog butter', a white waxy substance found in peat bogs in Scotland and Ireland. Bog butters are thought to have formed when bog-land communities buried fatty food substances hundreds of years ago, possibly for preservation purposes. Richard Evershed and colleagues have analysed nine samples of bog butter, concluding that two-thirds of them are derived from dairy products; the remainder being of animal-fat origin.
Stressed-out fish hold a clue to the environmental impact of acid rain. Norwegian researchers have monitored salmon in two rivers. Deposits of aluminium on their gills make the fish stressed, a phenomenon that can be tracked by measuring their blood glucose levels. Just how much aluminium is deposited is related to the pH of the water, which in turn is governed by other environmental factors. The work shows what impact the addition of lime to water sources might have on stabilising acidity of the water in fish catchment areas.
