title: (Z)-1,2:5,6-Di-O-isopropyl-idene-α-d-ribo-hexofuranos-3-ulose O-benzyl-oxime.
abstract: 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.
