摘要：

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 Knoevenagel 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. (C) 2008 Elsevier Ltd. All rights reserved.
