promoted Michael addition of the substituted acetonitriles to 2-hetaryl-2-(tetrahydro-2-furanyliden)acetonitriles followed by ring transformations has provided novel convenient synthetic methods to nitrogen bridgehead fused cyanopyridines bearing hydroxypropyl side chain. The structures of obtained compounds have been established based on NMR spectroscopy investigation and X-ray diffraction data.
