Treatment of alkynyloxiranes 3 with KO-t-Bu in t-BuOH causes isomerization to the furans 4.A pathway involving a cumulene alkoxide is proposed.
Base-catalyzed isomerization of alkynyloxiranes. A general synthesis of furans

Alkynyloxiranes 5, available through coupling of vinylic halides with terminal alkynes followed by epoxidation with MCPBA, are isomerized to furans 6 upon treatment with KO-t-Bu in t-BuOH-18-crown-6. The reaction has been employed for the synthesis of fur
