3,28-Diacet­oxy-29-bromo­betulin

In the title mol­ecule, C(34)H(53)BrO(4), all the cyclo­hexane rings adopt chair conformations, while the cyclo­pentane ring adopts an envelope conformation. In the crystal, weak inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into corrugated sheets parallel to the ab plane.
