Abstract

The title compound, C(15)H(18)O(3), was isolated from Lacta-rius piperatus (Fr.) S. F. Gary collected from the Kunming area in Yunnan province, China. The central cyclo-hexyl ring adopts a chair conformation, while the furan-one ring is close to planar (r.m.s. deviation = 0.0174 Å). The remaining methyl-ene cyclo-hexene ring has a flattened chair conformation. In the crystal, mol-ecules are linked via inter-molecular O-H⋯O and C-H⋯O hydrogen bonds into zigzag chains along the a axis.

摘要

标题化合物C(15)H(18)O(3)是从采自中国云南省昆明地区的辣乳菇（Lactarius piperatus (Fr.) S. F. Gary）中分离得到的。中心环己基环呈椅式构象，而呋喃酮环接近平面（均方根偏差 = 0.0174 Å）。其余的亚甲基环己烯环具有扁平的椅式构象。在晶体中，分子通过分子间的O—H⋯O和C—H⋯O氢键沿a轴连接成锯齿链。
