final R =0.054 for 648 observed reflections. The
molecule is propeller shaped. The benzoyl groups act as
protecting groups and the phenyl group is a base
substitute. The crystal structure does not involve any
intermolecular stacking interactions between the phenyl
groups. The molecules pack in typical herring-bone-like
arrays. The sugar has a fl-D configuration with
C(2')-endo-C(3')-exo pucker (2T3), pseudorotation
angle P = 172 (2) °, degree of pucker r m = 39 (2) °
