In the title mol-ecule, C(17)H(13)NOS(2), the essentially planar thia-zole ring (r.m.s deviation 0.005 Å) forms dihedral angles of 16.85 (8)° and 75.02 (8)° with the phenyl rings. The dihedral angle between the two phenyl rings is 61.95 (9)°.

In the title compound, C(14)H(17)NO(3), the dihedral angles show that the H atoms at two stereocenters are in a trans-diaxial configuration. In the crystal, the molecules are linked by O-H⋯O hydrogen bonds. The absolute configuration of the molecule has been established on the basis of refinement of the Hooft and Flack parameters.

The (R)-BINOL•SnCl4-catalyzed formal (3 + 2) cycloaddition between 3-substituted indoles and benzyl 2-trifluoroacetamidoacrylate is a direct, enantioselective method to prepare pyrroloindolines from simple starting materials. However, under the originally disclosed conditions, the pyrroloindolines are formed as mixtures of diastereomers, typically in the range of 3:1 to 5:1 favoring the exo-pro...

In the title compound, C(10)H(9)NOS(2), the five-membered heterocyclic ring and the benzyl moiety are oriented at a dihedral angle of 77.25 (4)°. In the crystal, infinite polymeric C(6) chains extending along [001] are formed due to C-H⋯O hydrogen bonds. C-H⋯π inter-actions link the chains, building up a three-dimensional network.

In the title compound, C(16)H(15)NOS, the thia-zolidine ring, which is essentially planar [maximum deviation = 0.071 (2) Å], makes dihedral angles of 88.01 (8) and 87.21 (8)° with the terminal phenyl rings. The dihedral angle between the phenyl rings is 49.45 (5)°. In the crystal, mol-ecules are linked by a weak inter-molecular C-H⋯O hydrogen bond, forming a supra-molecular chain along the b ax...

A series of 5-sulphanyl derivatives of 1-Benzyl-2-alkyl-4-nitro-1H-imidazoles (5-9) were prepared by the coupling method of 3-(1-Benzyl-2-ethyl-4-nitro-1H-imidazole-5ylsulfanyl)propanoic acid (4) with appropriate amino acid ester hydrochloride, in the presence of hydroxybenzotriazole (HOBT) and DCC. Compounds (10-12) and (13) were similarly synthesized using appropriate amino alcohols, and 1-su...

The emergence of strains of Schistosoma resistant to praziquantel has drawn attention to the search for new schistosomacide drugs. Imidazolidinic derivatives have performed outstandingly against adult S. mansoni worms when evaluated in vitro. The molecular modification of imidazolidine by way of bioisosteric replacement gives rise to variations in its biological response. This study verifies th...
