        abstract = {The Rh(I)-catalyzed allenic cyclocarbonylation reaction is a formal [2 + 2 + 1] cyclocarbonylation process that has been used to gain access to 4-alkylidenecyclopentenones. Inclusion of a six-membered ring on the tether between the allene and the alkyne components allows access to a variety of [6-7-5] ring structures found in the core-skeletons of natural products such as rippertene. This thesis describes a synthetic approach to the carbocyclic skeleton of 3{\ensuremath{\alpha}}-hydroxy-15-rippertene, utilizing the Rh(I)-catalyzed allenic cyclocarbonylation reaction. Starting from 2-butyn-1-ol the [6-7-5] carbocyclic core of rippertene was synthesized in 1.9\% over 10 steps.}
