B. Gabriele et G. Salerno, A NEW AND EFFICIENT SYNTHESIS OF ROSEFURAN - A GENERAL-SYNTHESIS OF FURANS BY PALLADIUM-CATALYZED CYCLOISOMERIZATION OF (Z)-2-EN-4-YN-1-OLS, Chemical communications, (12), 1997, pp. 1083-1084
(Z)-3,7-Dimethylocta-2,6-dien-4-yn-1-ol, readily available from (Z)-3-
methylpent-2-en-4-yn-1-ol, undergoes cycloisomerization in the presenc
e of catalytic amounts of K2PdI4 to give rosefuran in high yield.
