Synthesis andin vitro antifungal activity of 1-amino-3,4-dialkylnaphthalene-2-carbonitriles and their analogues
4-alkyl-substituted 1-aminonaphthalene-2-carbonitriles and their analogues were prepared and evaluated for growth-inhibiting activity against four phytopathogenic fungi: Fusarium culmorum, Alternaria brassicicola, Botrytis cinerea and Penicillium expansum. The results obtained were compared with the activity of a commercial fungicide. The highest fungistatic activity was revealed by amino nitriles having hydrogen atoms

Diastereoselectivity in the photoallylation and photoreduction of 1,1-dicyano-2-methyl-3-phenyl-1-butene by allyltrimethylsilane in the presence of phenanthrene was dependent on the structures and stoichiometry of the added carboxylic acids. Diastereoselectivity increased up to 72% by the addition of equimolar amount of l-lactic acid based on the alkene.
