Three potential precursors of trans-cyclonona-1,2,6-triene (1), namely the allene-dioxolan (7), the allene-oxathiolan (14), and the dichlorocyclopropane (16) have been prepared starting ultimately from cyclo-octa-1,5-diene.Treatment of these precursors with BunLi under conditions appropriate to each case gave 2,3-divinylcyclopentene in moderate to good yields.It is considered that trans-cyclonona-1,2,6-triene is formed as transient intermediate.
