Abstract:

The title compound, C20H21ClN2O5, has potential calcium modulatory properties. The 1,4-di­hydro­pyridine ring has the usual shallow boat conformation. The 2-chloro-5-nitro­phenyl ring is oriented such that the chloro substituent is in a synperiplanar orientation with respect to the 1,4-di­hydro­pyridine ring plane, while the nitro substituent sits over the 1,4-di­hydro­pyridine ring. The cyclo­hexenone ring has a conformation that is approximately half-way between that of an envelope and that of a half-chair. The mol­ecules are linked into chains by intermolecular N—H…O hydrogen bonds.
