Synthesis of 3-substituted coumarins via sequential pericyclic transformations of δ-aryloxymethylacrylic acids and enophiles

Tetrahedron Letters

α-Aryloxymethylacrylic acids and their derivatives have been found to undergo some novel thermal transformations leading to the formation of 'ene' dimers. The structure of the dimer has been revised on the basis of degradation studies, extensive spectral data and isolation of intermediates. © 1985.
