Single-Step Construction of a Nine-Membered Carbocycle by a New [4+4+1] Cycloaddition |

| Authors: | Masahiro Murakami Kenichiro Itami Yoshihiko Ito |
| Abstract: | A palladium catalyst serves as a template for the assembly of a nine-membered carbocycle from two molecules of vinylallene and one molecule of carbon monoxide Eq. (a)]. This unprecedented 4+4+1] cycloaddition is in marked contrast to the 4+1] cycloaddition mediated by rhodium(I ) catalysts. |
