In the title compound, C(11)H(14)Cl(3)NO(6), the fused five-membered oxazoline and tetra-hydro-furan rings are essentially planar with maximum deviations of 0.069 (1) and 0.031 (1) Å, respectively, and make a dihedral angle of 64.23 (11)° with each other. In the crystal, mol-ecules are linked by O-H⋯O and C-H⋯O hydrogen bonds, forming chains along the b-axis direction. Further C-H⋯O hydrogen bonds are observed between the chains.
在标题化合物C₁₁H₁₄Cl₃NO₆中,稠合的五元恶唑啉环和四氢呋喃环基本呈平面状,最大偏差分别为0.069 (1) Å和0.031 (1) Å,且彼此间形成的二面角为64.23 (11)°。在晶体中,分子通过O—H⋯O和C—H⋯O氢键相连,沿b轴方向形成链状结构。在这些链之间还观察到进一步的C—H⋯O氢键。
