AbstractOrganocatalytic azide–ketone [3+2] cycloaddition (OrgAKC) of a variety of 1‐aryl‐2‐(arylthio)ethanones and 1‐alkyl‐2‐(alkylthio)ethanones with different aryl or alkyl azides is reported in dimethyl sulfoxide or solvent‐free under ambient conditions to furnish 1,5‐disubstituted 4‐thio‐1,2,3‐triazoles in a regiospecific manner, which are further converted into useful 1,5‐disubstituted 1,2,3‐triazoles by treatment with Raney Ni at 25 °C for 1–3 h. Notable features of the OrgAKC reaction include high rate and selectivity, solvent‐free conditions, easily available substrates and catalysts, a wide range of synthetic and medicinal applications, and excellent yields generating a vast library of triazoles.

could be linked to their chemistry or structural conformation. The triazolines and triazoles evince anticonvulsant activity as a class and compare very well with the prototype antiepileptic drugs--ethosuximide, phenytoin, phenobarbital, valproate--in their anticonvulsant potency and minimal neurotoxicity. They have emerged as a new generation of anticonvulsant agents that show great promise as potentially
