In the title compound, C(28)H(35)N(3)O(4), also known as 14-de-oxy-paraherquamide A,the two pyrrolidine rings adopt envelope conformations. The piperazine ring of the diaza-bicyclo-[2.2.2]octan-3-one unit adopts a boat conformation whereas the two piperidine rings are in distorted boat conformations. Intra-molecular C-H⋯O hydrogen bonds are observed. In the crystal, the mol-ecules are linked into chains along the b axis by inter-molecular N-H⋯O hydrogen bonds.
