Investigations of a Rh(I)-catalyzed cyclocarbonylation reaction reveal its general synthetic utility for accessing highly functionalized tricyclic [6-7-5] linear and angular ring systems from allene-ynes. Three types of allene-ynes were prepared and subjected to Rh(I)-catalyzed cyclocarbonylation conditions. For three series of allene-ynes, the [6-7-5] ring systems were afforded in varying yields depending on the substrate structure. One series of allene-ynes afforded the [6-6-5] ring system possessing an alpha-alkylidene cyclopentenone as a result of a selective reaction with the proximal double bond of the allene.

Cyclization of allene-containing aryl and alkenyl halides under the influence of a catalytic amount of a Pd-phosphine complex, e.g., Cl2Pd(PPh(3))(2), proceeds via carbon-carbon bond formation at the central carbon atom of the allene moiety, providing a novel and facile route to seven- and eight-membered cycloalkene derivatives.
