Abstract: The King reaction of α,β-unsaturated γ - and δ-lactones having a reactive methyl group in position β was studied for the first time. These compounds, reacting with pyridine derivatives, afforded quaternary pyridinium salts which were tested for antimicrobial activity. An α,β-unsaturated α-cyano ester, an open-chain analogue of the above-mentioned lactones, was also used in the reaction.
