3,28-Diacet-oxy-29-bromo-betulin.


ABSTRACT: In the title mol-ecule, C(34)H(53)BrO(4), all the cyclo-hexane rings adopt chair conformations, while the cyclo-pentane ring adopts an envelope conformation. In the crystal, weak inter-molecular C-H?O hydrogen bonds link the mol-ecules into corrugated sheets parallel to the ab plane.
