Abstract
3-Arylidene-4-chromanones undergo regioselective 1,3-dipolar cycloaddition reactions with N-metalated azomethine ylides derived from aromatic aldimine s of glycine methyl ester in the presence of silver acetate and triethylami ne to give spiropyrrolidine derivatives in good yield. X-Ray crystal struct ure analysis of one of the products confirms the structure and regiochemist ry of the cycloadditions. (C) 2001 Elsevier Science Ltd. All rights reserve d.
