This paper reports a phosphine-catalyzed [2+3] annulation reaction between aurone-derived azadienes and amino crotonates, yielding a series of spiro[benzofuran-tetrahydropyrrole] compounds bearing three consective sterecenters in high yields with moderate to excellent diastereoselectivities. The structures of the desired products were determined by a combination of NMR sprctroscopy, high-resolution mass spectrometry (HRMS) and X-ray single crystal diffraction analysis. This method has the advantages of simple operation, broad substrate scope and 100% atom economy, which provides a new idea for the effecient construction of spiro[benzofuran-tetrahydropyrrole] compounds.

Key words: phosphine catalysis, [2+3] annulation, aurone-derived azadienes, amino crotonates, spirocyclic compounds
