1-(5-Hy-droxy-2,2,8,8-tetra-methyl-2H,8H-pyrano[2,3-f]chromen-6-yl)ethanone.

ABSTRACT: In the title compound, C(18)H(20)O(4),the pyran ring of the chromene unit adopts a half-chair conformation. An intra-molecular O-H?O hydrogen bond occurs. In the crystal, mol-ecules are linked along the b axis by C-H?O hydrogen bonds.
