Numerous derivatives of spiropyrrolidines and spiropyrrolizines containing cyano groups were successfully synthesized via condensation of sarcosine and proline Schiff bases of several aromatic aldehydes with the Kn?evenagel adduct of 9-fluorenone-malononitrile prepared through a modified procedure. Assignment of the molecular structure was carried out by single crystal X-ray diffraction, as well as by HMBC and ROSEY spectroscopy.
