In the title compound, C22H18FNO3S2, the five-membered thiazolidine ring is planar (r.m.s. deviation = 0.003 Å) and forms dihedral angles of 70.2 (3), 73.16 (17) and 10.32 (14)° with the cyclopropane, fluorobenzene and methylthiobenzene rings, respectively. The sum of the bond angles around the thiazolidine ring N atom (359.6°) indicates sp2 hybridization. The molecular structure features intramolecular C—HS, C—HF and C—HO interactions. In the crystal, no significant intermolecular contacts were apparent.

In the title compound, C39H38N2O4, the pyridinone ring adopts a twisted half-chair conformation with the N atom deviating by 0.3304 (1) and with the methylene C atom adjacent to the octahydroindolizine unit deviating by 0.444 (3) Å from the mean plane defined by the other four atoms. In the octahydroindolizine system, the pyrrolidine ring exhibits an envelope conformation, with the fused methyne C atom deviating by 0.6315 (1) Å from the mean plane defined by the other four atoms, and the piperidine ring exhibits a distorted chair conformation, as reflected in the puckering parameters Q = 0.568 (4) Å, θ = 1.5 (4) and φ = 161 (16)°. In the crystal pairs of weak C—HO interactions form centrosymmetric dimers, which are further connected by C—Hπ interactions. The crystal studied was a non-merohedral twin, with a domain ratio of 0.91:0.09.
