| Popis: | The synthesis of a series of bicyclo[4.2.2]octenones and bicyclo[3.2.2]heptenones by 1,3- or 1,2-migration reaction from 2-vinylbicyclo[2.2.2]octenols is reported. These ring-expansion reactions were accomplished under basic or neutral conditions. Whether 1,3- or 1,2-migration takes place depends on endo- or exocyclic olefin displacement in the substrates. |
