vinylpyridines with variously substituted phenyl azides, clearly indicates that the electron donating methyl and methoxy groups on the phenyl azide facilitate reaction, while the electron withdrawing nitro group has a retarding effect. This is consistent with an increase in the HOMOazide energy and hence in azide reactivity. According to the FMO model, the 1,3-cycloaddition of aryl azides to vinylpyridines

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
