1,7,8-Tri-O-acetyl-6-O-benzoyl­castanospermine

The title compound (alternatively 1,7,8-tri­acetoxy­per­hydro­indolizin-6-yl benzoate), C21H25NO8, was obtained during studies of castanospermine derivatives. The crystal structure consists of independent mol­ecules with only van der Waals contacts. The fused six- and five-membered rings adopt chair and twist conformations, respectively.
