(S)-1-[(S)-4-Benzyl-2-thioxothiazolidin-3-yl]-3-hydroxybutan-1-one

The title compound, C(14)H(17)NO(2)S(2), was synthesized by asymmetric aldol condensation of N-acyl-thia-zolidinethione with acetaldehyde. In the mol-ecule, the thia-zolidine five-membered ring assumes an envelope conformation. Inter-molecular C-H⋯O and intra-molecular O-H⋯O and C-H⋯S hydrogen bonding helps to stabilize the structure.

(S)-3-[(S,E)-4-(4-Chlorophenyl)-1-nitrobut-3-en-2-yl]thian-4-one

The title compound, C(15)H(16)ClNO(3)S, was obtained by the organocatalytic asymmetric Michael addition of thian-4-one to 1-chloro-4-[(1E,3E)-4-nitro-buta-1,3-dien-yl]benzene. The double bond has an E configuration and the thian-4-one six-membered ring adopts a chair conformation. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

Synthesis and Antibacterial Evaluation of (S,Z)-4-methyl-2-(4-oxo-5- ((5-substituted phenylfuran-2-yl) methylene)-2-thioxothiazolidin-3-yl) Pentanoic Acids

The resistance of antimicrobials has become a global hazard with the irrational use of antibiotics. Infection of drug-resistance bacteria seriously threatens human health. Currently there is an urgent need for the development of novel antimicrobial agents with new mechanisms and lower levels of toxicity. In this paper, a series of (S,Z)-4-methyl-2-(4-oxo-5-((5-substitutedphenylfuran-2-yl) methy...
