6?-Hy-droxy-eremophil-7(11)-en-8?,12-olide.

ABSTRACT: The title eremophilenolide, C(15)H(22)O(3), is a natural compound isolated from Senecio laetus Edgew. The two cis-fused six-membered rings have chair confomations and the five-membered ring has a planar envelope conformation [maximum deviation = 0.010?(1)?Å]. The ?-hy-droxy group participates in inter-molecular O-H?O hydrogen bonding, forming mol-ecular chains along the a axis.

The title eremophilenolide, C(15)H(22)O(3), is a natural compound isolated from Senecio laetus Edgew. The two cis-fused six-membered rings have chair confomations and the five-membered ring has a planar envelope conformation [maximum deviation = 0.010 (1) Å]. The β-hy-droxy group participates in inter-molecular O-H⋯O hydrogen bonding, forming mol-ecular chains along the a axis. ...[more]
