Description
Summary:In the title compound, C29H27N3O5, the hydropyran ring adopts an envelope conformation with the methine C atom bearing the para-meth-oxy-benzene 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 intra-molecular C-H⋯O contact closes an S(7) ring. In the crystal, inversion dimers linked by C-H⋯O inter-actions generate R 2 (2)(18) loops and N-H⋯O hydrogen bonds connect the dimers into [100] chains.
