The sequential reaction of furfural with cyclic secondary amines and further with benzaldehyde and cyanoacetates affords new 2,4-dicyano-8-(R2N)-6-oxo-3-phenylbicyclo[3.2.1]-octane-2,4-dicarboxylates as rac-(1R,2R,3R,4S,5S,8R)-diastereomers. The structures of the reaction products were determined by X-ray diffraction.
