Abstract

2H-Cyclohepta[b]furan-2-one (1) reacted with TPT, electrophilically to give 3-dihydropyridinyl-2H-cyclohepta[b]furan-2-one and subsequent treatment with sodium hydroxide in ethanol gave 3-(4-pyridinyl)-2H-cyclohepta[b]furan-2-one in excellent yields. Furthermore, it reacted with methyl iodide give a corresponding pyridinium salt easily.
