An anti-tetraamination of a 1,3-diene unit via cascade annulations of the azulenone scaffold with dicarbonyl azo-compounds
Ishigaki, Yuhei,Mahendar, Velisoju,Oguri, Hiroki,Oikawa, Hideaki
, p. 3304 - 3305 (2010)
Dense and stereo-controlled integrations of C-N bonds on the azulenone scaffold are achieved by sequential (i) ene, (ii) [6+2]-cycloaddition, and (iii) hetero-conjugate addition reactions leading to a topologically complex bis-bridged skeleton.
Selective bond cleavage of [5.3.1]propellanes by lead tetraacetate: A facile entry into the carbocyclic frame [A,B ring] of taxol

[5.3.1]Propellanes e.g., the tricyclo[5.3.1.01,7]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 construction of carbocylic frame of A,B ring of Taxol.
