Abstract
Microwave-assisted synthesis of ferrocenyl pyrrolizidines containing cyano groups has been accomplished in moderate yields via a facile [3+2]-cycloaddition reaction of several azomethine ylides, derived from aromatic aldehydes and proline, with 1, 1-dicyano-2-ferrocenylethene as the dipolarophile. This method offers several advantages such as short reaction time and simple procedure.
