Daia, G.Elena, Gabbutt, Christopher D., Hepworth, John D., Heron, B. Mark, Hibbs, David E. and Hursthouse, Michael B. (1998) The directed lithiation of some 3-acylchromone acetals. Tetrahedron Letters, 39 (10). pp. 1215-1218. ISSN 0040-4039Metadata only available from this repository.
3-Acylchromone acetals are lithiated at C-2. Subsequent electrophilic trapping gives chromones 4 together with a ring-contracted dimer 6. During the formation of some acetals, an acid-catalysed rearrangement to a 2-substituted 3-formylchromone acetal is observed.
