Abstract
Tautomerism of clitidine (1a), a toxic pyridine nucleoside from the po isonous mushroom Clitocybe acromelalga, was investigated by N-15 NMR s pectroscopy in aqueous solution and by X-Ray crystallographic analysis in the solid state, which showed the tautomer (1d) to be predominant in both states.
