title: (+)-(1S,5R,6R)-6-[(S)-1-Hy-droxy-2-(meth-oxy-meth-yloxy)eth-yl]-1-methyl-3-trichloro-methyl-2-aza-4,7-dioxa-bicyclo-[3.3.0]oct-2-en-8-one.
abstract: 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.
