Slow progression of CDK. Renal diets are modified from upkeep diets in numerous strategies including supplementation with (n-3) polyunsaturated fatty acids plus the addition of antioxidants. A proinflammatory eating plan,…
The group of Shujiang Tu from Xuzhou Normal University, China, has reported on the synthesis of a series of pyridopyrimidine-4,7-diones (Org. Biomol. Chem. 87789-35-3 In stock 2007, 7, ASAP.DOI: 10.1039/b617201f).…
The group of Hans Adolfsson from Stockholm University has shown that ketones can be reduced to the corresponding alcohols via transfer hydrogenation in the absence of a transition metal catalyst…
The enantioselective reduction of ketones byalcohol dehydrogenases is a valuable synthetic procedure, but the required co-factors are expensive. If the reduction can be carried out with intact cells, the expense…
A key step in the Gin synthesis of the hetesine alkaloid nominine reviewed last week ( 2007, August 6) was an intramolecular Diels-Alder reaction. There have been several other recent…
