Abstract

A regio- and stereoselective method for the synthesis of spiro[acenaphthylenepyrroli(zi)din]-2-ones containing a 1,3-diketone fragment in their structure in 57–93% yields was developed. The method is based on (3+2) cycloaddition of azomethine ylides generated in situ from acenaphthenequinone and α-amino acids (L-(thia)proline, L-phenylglycine) to (E)-1,5-diarylpent-4-ene-1,3-diones in EtOH at 60–70°C for 4–8 h.
