Diethyl 1-benzyl-2,2-dioxo-4-phenyl-3,4,6,7,8,8a-hexahydro-1H-pyrrolo[2,1-c][1,4]thiazine-1,3-dicarboxylate

In the title compound, C26H31NO6S, the five-membered pyrrolidine ring adopts an envelope conformation and the six-membered thiazine ring is in a distorted chair conformation. The crystal packing is stabilized through an intermolecular C—H...O interaction, generating inversion-related R22(10) ring motifs.
