,28-diacetateAbstract: The triterpene 20(29)-lupene-3,28-diacetate, C34H54O4, was obtained by acetylation of naturally occurring betulin. The cyclopentane ring adopts a twisted envelope conformation and the cyclohexane rings are all in chair conformations. The molecular structure is stabilized only by weak intramolecular C-H
O hydrogen bonds.
