Daia, G.Elena, Gabbutt, Christopher D., Hepworth, John D., Heron, B. Mark, Hibbs, David E. and Hursthouse, Michael B. (2002) Synthesis and cycloadditions of 9H-furo[3,4-b][1]benzo(thio)pyran-9-ones: furan ring formation by a novel hydrolytically induced cycloreversion. Tetrahedron Letters, 43 (25). pp. 4507-4510. ISSN 0040-4039

C-2 lithiation of acetals 2 followed by trapping with aldehydes gives 3. Subsequent unmasking of the acetal function provides furobenzo(thio)pyrans 4, cycloadditions of which have been investigated.
