In the title compound, C 29 H 27 N 3 O 5 , the hydropyran ring adopts an envelope conformation with the methine C atom bearing the  para -meth­oxy­benzene ring as the flap. The central pyrrolidine ring has a twist conformation on the N—C bond involving the spiro C atom. The piperidine ring adopts a chair conformation. An intra­molecular C—H⋯O contact closes an  S (7) ring. In the crystal, inversion dimers linked by C—H⋯O inter­actions generate  R   2   2 (18) loops and N—H⋯O hydrogen bonds connect the dimers into [100] chains.

6-(4-Methoxyphenyl)-6a-nitro-6,6a,6b,7,8,9,10,12a-octahydrospiro[chromeno[3,4-a]indolizine-12,3′-indolin]-2′-one
