A cyanoethylation of 2-acetyl-5-R-furans, 1-nitro-2(5-R-2-furyl)ethanes, an
d 2-nitro-1-(2-furyl)propane was investigated. The optimum conditions were
determined for preparation of monocyanoethylated products: nitriles of 5-ox
o-5-(5-R-2-furyl)pentanoic and 4-nitro-5-(5-R-2-furyl)pentanoic acids. The
cyanoethylation of furyl-containing nitroethanes with excess acrylonitrile
provided bisadducts, dinitriles of 4-nitro-4-(5-R-furfuryl)heptanedionic ac
ids.
