Abstract:

The reaction of furfural with secondary amines and isopropyl cyanoacetate leads to the formation of the previously unknown diisopropyl 8-(dialkylamino)-2,4-dicyano-3-(2-furyl)-6-oxobicyclo[3.2.1]octane-2,4-dicarboxylates. The tructure of the products was confirmed by NMR and X-ray analysis.

Keywords: furfural, isopropyl cyanoacetate, Stenhouse salt, Nazarov reaction, carbocyclization, bicyclo[3.2.1]octane
