Regiochemistry in alkylation, acylation and methoxycarbonylation of alkali salts from 2-substituted alkenylpropanedinitriles
Autor: Per Kolsaker, Christian Rømming, Hege Karlsen, Pål Songe, Lise Cathrine Hagen, Lise Kristin Sunsby
Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :497-507
Alkali salts (4−) of several 2-substituted alkenylpropanedinitriles are prepared, isolated and characterised by 1H and 13C NMR spectroscopy. By treating the salt 4a− with 4a a dimer, 2-dicyanomethylene-6-methyl-4,6-diphenyl-1,2,5,6-tetrahydronico

Publikováno v: Mycopathologia. 152:23-34
Twenty-three Fusarium culmorum and 21 F. graminearumisolates were studied for their ability to produce mycotoxins and other secondary metabolites. The strains were cultivated on rice, and the extracts analysed by gas chromatography mass spectrometry
