Özet

A highly efficient method for the synthesis of 2-pyridonyl alcoholsviagold(i) catalyst was developed. The effect of methanesulfonic acid on the reaction progression with the gold catalyst was determined. The proposed mechanism involves intramolecular cyclization product formation derived from 5-exo-digand 6-exo-digaddition of the nitrogen for 2-propargyloxypyridine and 2-(but-3-yn-1-yloxy)pyridine, respectively. The pyridinium salt formed by the gold(i) catalyst and methanesulfonic acid undergoes a rearrangement reaction in a weakly basic medium (5% aq. Na2CO3) to formN-alkenyl pyridonyl alcohols.N-alkenyl pyridonyl alcohols can be obtained in moderate to excellent yields using this method.
