The title compound, C(22)H(27)NO(11), was synthesized by the reaction of 4,5-diacet-oxy-6-acetoxy-methyl-3-amino-tetra-hydro-pyran-2-yl acetate and 2-hydr-oxy-3-methoxy-benzalde-hyde in ethanol. The mol-ecule contains two six-membered rings, one of which is in a chair conformation, and an intra-molecular O-H⋯N hydrogen bond is present.
