Dimethyl 3,4,5,5-tetraphenyl-1,3-thiazolidine-2,2-dicarboxylate and 3,3-dichloro-2,2,4,4,3'-pentamethyl-r-2',t-4'-diphenylcyclobutane-1-spiro-5'-1,3-thiazolidine

Abstract: The first of the title compounds, C₃₁H₂₇NO₄S, (V), crystallizes in the monoclinic space group P2₁/c with two independent molecules in the asymmetric unit, while the second, C₂₃H₂₇Cl₂NS, (IX), crystallizes in the orthorhombic space group Pbca with one molecule in the asymmetric unit. In both crystal structures, the 1,3-thiazolidine ring adopts a half-chair conformation. The crystal structures are stabilized by weak C-HO and C-HCl hydrogen bonds in (V) and (IX), respectively.

Formula: C₃₁H₂₇NO₄S and C₂₃H₂₇Cl₂NS
