The title compound, C12H14O6, has been isolated from a Fries reaction on 3,6-dihydroxy-2,4-dimethoxyacetophenone. Its molecular structure contains an intramolecular hydrogen-bonded unit involving the -COCH3 and -OH substituents. The best plane through the acetoxy group makes a dihedral angle of 88.74 (5)° with the plane of the aromatic ring.

A practical and economical high-yielding, six-step sequence synthesis of a flavone: Application to the multigram-scale synthesis of ladanein
Herein we report a short and economic synthesis of the antiviral flavonoid lead ladanein (1). Ladanein is obtained from 2,6-dimethoxyquinone (11) in six steps with 51% overall yield. After a high-yielding reductive acetylation and Fries rearrangement, the
