ABSTRACT
THE TITLE SESQUITERPENE [SYSTEMATIC NAME: 6-methoxy-10-methyl-7-(propan-2-yl)-2-oxatricyclo[6.3.1.0(4,12)]dodeca-1(11),4,6,8(12),9-pentaen-5-ol], C(16)H(18)O(3), was isolated from pathogen-infected stele tissue of Gossypium barbadense. There are two mol-ecules in the asymmetric unit and the dihedral angle between their naphtho-furan systems is 86.48 (2)°. In the crystal, O-H⋯O hydrogen bonds between the hy-droxy groups and etheric O atoms link the mol-ecules into centrosymmetric tetra-mers. These tetra-mers are assembled into (010) layers via stacking inter-actions between the naphtho-furan systems [inter-planar distance 3.473 (3) Å] and short C-H⋯O contacts.
