Direct catalytic asymmetric addition of allylic cyanides to N-diphenylphosphinoyl ketoimines with a bimetallic catalytic system comprising Ph-BPE/[Cu(CH3CN)4]ClO4/LiOAr is described. Intermediary alpha-adducts readily isomerized to afford synthetically useful alpha,beta-unsaturated nitriles bearing an optically active tetrasubstituted carbon. Applicability to aromatic, heteroaromatic, and
The soil-borne fungal pathogen Verticillium longisporum is able to penetrate the root of a number of plant species and spread systemically via the xylem. Fumigation of Verticillium contaminated soil with Brassica green manure is used as an environmentally friendly method
Animals exposed to allylnitrile develop permanent abnormalities in motor behaviour, similar to those caused by 3,3'-iminodipropionitrile (IDPN) and crotononitrile. IDPN and crotononitrile effects have been attributed to vestibular hair cell degeneration, but allylnitrile has been suggested to modify behaviour through

We report that a hard Lewis base substantially affects the reaction efficiency of direct catalytic asymmetric gamma-addition of allyl cyanide (1a) to ketones promoted by a soft Lewis acid/hard Brønsted base catalyst. Mechanistic studies have revealed that Cu/(R,R)-Ph-BPE and Li(OC(6)H(4)-p-OMe)

The formation of plant-derived biomolecules during sauerkraut fermentation was studied. Cabbage was fermented with a starter culture, and the results were compared to the results of spontaneous fermentation. The concentration of flavonoids and glucosinolates was analyzed by HPLC, and that
