The central six-C-atom chain of the title compound, C52H50O10, adopts a nearly planar extended conformation free from C//C, C//O and O//O 1,3-parallel interactions. The three torsion angles formed by these atoms have values of 177.4 (2), 174.2 (2) and -178.0 (2)degrees. The bulky triphenylmethyl groups, which are oriented gauche to their neighboring acetoxy groups with O-C-C-O torsion angles of -69.8 (2) and -63.0 (2)degrees, cause no distortion of the bond lengths and bond angles of the sugar moiety.
