چکیده
The mol-ecule of the title compound, C(13)H(21)NO(8), consists of two methyl-enedi-oxy rings and one tetra-hydro-furan ring. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into helical chains running along the 6(1) screw axis. Weak inter-molecular C-H⋯O hydrogen bonds help to stabilize the crystal packing. Voids of 245 Å(3) per unit cell occur.

The title compound, C(19)H(25)NO(6), is a Z diastereomer in which the phenyl ring of the 3-benzyl-oxime substituent and the 5,6-O-isopropyl-idene acetal are both located on the Si-face of the C=N double bond. Inter-molecular C-H⋯O inter-actions result in helical chains along the b axis of the monoclinic unit cell.
