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

Abstract

In the title compound, C 26H 31NO 6S, the fivemembered pyrrolidine ring adopts an envelope conformation and the sixmembered thiazine ring is in a distorted chair conformation. The crystal packing is stabilized through an intermolecular C - H⋯O interaction, generating inversionrelated R 2 2(10) ring motifs.
