Abstract
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 atom s have values of 177.4 (2), 174.2 (2) and -178.0 (2)degrees. The bulky triphenylmethyl groups, which are oriented gauche to their neighborin g 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 t he sugar moiety.
