[5.3.1] Propellanes e.g., the tricyclo[5.3.1.0(1,7)]undeca-2,4-dien-10-one 8 and the corresponding methylidene compound 10 were prepared from methyl cinnamate 2 in several steps involving rhodium(II) acetate mediated cyclization of 4 to 6 as a key step. The selective central cyclopropyl bond cleavage in 8 and 10 by lead tetraacetate provides the basis of a new approach to the constriction of carbocyclic frame of A,B ring of Taxol.
