1-(5-Hy­droxy-2,2,8,8-tetra­methyl-2H,8H-pyrano[2,3-f]chromen-6-yl)ethanone

In the title compound, C(18)H(20)O(4),the pyran ring of the chromene unit adopts a half-chair conformation. An intra­molecular O—H⋯O hydrogen bond occurs. In the crystal, mol­ecules are linked along the b axis by C—H⋯O hydrogen bonds.
