Abstract: In the title compound, C29H27N3O5, 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-HO contact closes an S(7) ring. In the crystal, inversion dimers linked by C-HO interactions generate R22(18) loops and N-HO hydrogen bonds connect the dimers into  chains.
