Sažetak
Two independent molecules of the title compound adopt the ring-twisted conformation (b), defined by roughly orthogonal bridgehead torsion angles (N13-C14-C15-N17 = 95.1(3) and N23-C24-C25-N27 = 97.1(3)degrees). Stereoelectronically controlled ring-opening at the N3-C4 bond in the course of acidic hydrolysis thus occurs at the acid aminal stage of the multistep reaction [ref. 4] via a conformational change to the proper ring-twisted conformer (a).
