Abstract
In the title compound, C28H35N3O4, also known as 14-deoxyparaherquamide A,the two pyrrolidine rings adopt envelope conformations. The piperazine ring of the diazabicyclo[2.2.2]octan-3-one unit adopts a boat conformation whereas the two piperidine rings are in distorted boat conformations. Intramolecular C—H⋯O hydrogen bonds are observed. In the crystal, the molecules are linked into chains along the b axis by intermolecular N—H⋯O hydrogen bonds.
