Hydroxyphenyl-1-methylpyridinium-iodide as Potential Reactivators of Acetylcholinesterase Poisoned with Organophosphorus Compounds

It was our aim to reactivate acetylcholinesterase poisoned with sarin.We synthesized 2-(o-hydroxyphenyl)-1-methylpyridinium-iodide (9), 2-(p-hydroxyphenyl)-1-methylpyridinium-iodide (19) and 4-(o-hydroxyphenyl)-1-methylpyridinium-iodide (14) as potential reactivators.All substances showed moderate toxicity against mice; their reactivity potency in vitro and in vivo was negligible.

Intramolecular Addition of Enolates to Pyridinium Ions: Formation of Spiro

Intramolecular addition of ketone and ester enolates to N-alkylpyridinium species produced spiro in 82-93percent yields.When the ketone adducts were treated with hydriodic acid in ethanol at room temperature and the est
