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…
Several new methods for C-N ring construction based on enantioselective addition to imines have been reported. Michael J. Krische of University of Texas at Austin has used (J. Am. Chem.…
Peter W. Roesky of the Freie Universität Berlin has devised (Chem. Commun. 2006, 874. DOI: 10.1039/b514242c)a La catalyst that effects hydrosilylation of a terminal alkene 1 to 2. Sjoerd Harder…
The development of new methods for carbon-carbon bond formation is at the heart of organic synthesis. 2-(Difluoromethyl)pyridin-4-amine Data Sheet The most desirable methods are those that are easily practiced at…

Ry CapacityOxygen uptake measurements in suspended tumor cells and isolated rat brain mitochondriaThe OCR in suspended intact cells and isolated rat brain mitochondria was measured employing a high-resolution respirometer (OROBOROS…
Enantioselective allylation is one of the most commonly used methods for constructing secondary alcohols with high enantiocontrol. Hisashi Yamamoto of the University of Chicago has introduced (J. Am. Chem. Soc.…
Alkene metathesis has become part of the toolkit of organic synthesis. PMID:24182988 Nevertheless, there is room for improvement in catalyst efficiency. 3-Isopropylpyridin-2(1H)-one web Robert H. Grubbs of the California Institute…
Gentle tapping of a terminal alkene specifically to the corresponding methyl-substituted internal alkene is a potentially value-adding transformation, as illustrated by the conversion of the inexpensive allylated ketone 1 to…
