A series of newmethyl [2‐(arylmethylene‐hydrazono)‐4‐oxo‐thiazolidin‐5‐ylidene]acetates (5a–o) were synthesized via cyclocondensation of thiosemicarbazones (3a–o) with dimethyl but‐2‐ynedioate (4) in good yields under solvent‐free conditions. The environmentally friendly solvent‐free protocol overcomes the limitations associated with the customary protracted solution phase synthesis and afforded the
The chemical synthesis of a series of lignin-derived nitrogenated compounds was performed in high yields (73–99%) through simple conventional chemical transformations starting from natural monomers such as vanillin, syringaldehyde or 3,4-dihydroxybenzaldehyde. The study of the vanillin-derived compounds as substrates for commercially available laccases from Trametes versicolor and Myceliophthora thermophila

Electrical energy offers numerous benefits for performing synthesis, including increased reaction rates, enhanced yields, and cleaner chemistries. 5-Substituted-2-amino-1,3,4-oxadiazoles were synthesized directly from the semicarbazone at a platinum electrode under controlled potential electrolysis in an undivided cell assembly in acetonitrile. The compounds were screened for antibacterial and antifungal activity against Staphylococcus aureus, Klebsiella pneumoniae, Pellicularia salmonicolor, and Macrophomina phaseolina.
