Synthesis of (5Z)-3-Allyl-5-{[5-(4-methoxyphenyl)thiophen-2-yl]methylidene}-2-sulfanylidene-1,3-thiazolidin-4-one in L-Proline-Based Deep Eutectic Solvent
Résumé
3-N-allylrhodanine was condensed with 5-(4-methoxyphenyl)-thiophene-2-carbaldehyde in an L-proline-based deep eutectic solvent (DES) to obtain the π-conjugated heterocyclic rhodanine compound (5Z)-3-allyl-5-{[5-(4-methoxyphenyl)thiophen-2-yl]methylidene}-2-sulfanylidene-1,3-thiazolidin-4-one (2). Compound 2 was characterized by NMR spectroscopy, and its UV-vis spectrum was compared with that of the related derivative 3-allyl-5-(4-methoxybenzylidene)-2-sulfanylidene-1,3-thiazolidin-4-one (1). Preliminary results revealed that compound 2 is emissive at room temperature in solution.
