Abstract

The reactivity of 2,2,6,8-tetramethyltricyclo(6.2.2.01,6)dodecene (2) toward different metal salts has been explored. In the presence of Fe(II), Sn(II) and Ce(IV) ions, compound 2 underwent a rearrangement process to afford acyclic triketones Z-3 and E-3. The action of Zn powder in acetic acid resulted in an unexpected formation of furan 4 in high yield.

This yield is a great improvement compared with that previously reported [10] (3% yield).
