Syntheses of 6-8-5 tricyclic ring systems by carbonylative [2+2+1] cycloaddition of bis(allene)s

Shafawati, M.T. Soraya,Inagaki, Fuyuhiko,Kawamura, Takamasa,Mukai, Chisato

, p. 1509 - 1515 (2013/02/23)

The synthetic route for the construction of the 6-8-5 tricyclic carbon frameworks has been developed. The [RhCl(CO)dppp]2-catalyzed intramolecular Pauson-Khand-type reaction of the bis(allene)s, derived from dimedone, provided the corresponding
