8-[(3,3-Dimethyloxiran-2-yl)methoxymethyl]-11-hydroxy-2-isopropenyl-5-methyl-12-oxo-1,2,3,12-tetrahydropyrano[3,2-a]xanthen-1-yl acetate
The title compound, commonly known as 14-methoxytajixanthone-25-acetate, C(28)H(30)O(8), was isolated from Emericella variecolor. The central xanthone core is approximately planar (r.m.s. deviation = 0.084 Å). The dihydropyran ring adopts a distorted half-chair conformation. The oxirane plane is o...

| description | The title compound, commonly known as 14-methoxytajixanthone-25-acetate, C(28)H(30)O(8), was isolated from Emericella variecolor. The central xanthone core is approximately planar (r.m.s. deviation = 0.084 Å). The dihydropyran 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 intramolecular O—H⋯O hydrogen bond forms an S(6) ring. In the crystal, molecules are linked into a two-dimensional network parallel to the ab plane by weak intermolecular C—H⋯O hydrogen bonds. |
