Abstract

The title compound, commonly known as 14-methoxy-tajixanthone-25-acetate, C28H 3 0O 8 , was isolated from Emericella variecolor. The central xanthone core is approximately planar (r.m.s. deviation = 0.084 Å). The dihydro-pyran ring adopts a distorted half-chair conformation. The oxirane plane is oriented at an angle of 63.3 (2)° with respect to the phenol group. An intra-molecular O- H⋯O hydrogen bond forms an S(6) ring. In the crystal, mol-ecules are linked into a two-dimensional network parallel to the ab plane by weak inter-molecular C- H⋯O hydrogen bonds.
