The crystal structure and absolute configuration of the title compound, C17
H21BrO8, have been determined by X-ray analysis. They confirmed the 1'R abs
olute configuration at the 1'-bromoethyl moiety which has been assigned pre
viously on the basis of chemical and spectroscopic data. Cohesion of the cr
ystal can be attributed to weak intermolecular C-H ... O and van der Waals
interactions.
