Abstract
Starting from 4-cycloheptenone 4 the [7.4.1]enediyne 17 as well as the [7.3.2]eneyne-allene 20 were prepared. Whereas the enediyne 17 turned out to be a reactive compound, the eneyne-allene 20 surprisingly was found to be stable at room temperature. The formation of the eneyne-al lene 20 is explained by invoking a dyotropic rearrangement, followed b y a valence isomerization of a propyne substructure.
