Abstract

The title compond, C(26)H(44)N(2)O, is an steroidal alkaloid isolated from the medicinally important plant Sarcococca saligna. The mol-ecule consists of four fused rings (A-D), having chair, half-chair, chair and envelope conformations, respectively. The dimethyl-amino group is axially oriented on ring A, whereas the (N-methyl-acetamido)-ethyl group is attached equatorially on ring D. The crystal structure is stabilized only by van der Waals forces.
