Formation of bicyclo[3.2.1]octane, bicyclo[4.2.1]nonane, and bicyclo[3.3.1]nonane by transannular radical cyclisations
Abstract
Cyclohept-4-enylmethyl radicals undergo transannular cyclisation to give bicyclo[3.2.1]octane; likewise, bicyclo[4.2.1]nonane and bicyclo[3.3.1]nonane are obtained from cyclo-oct-4-enylmethyl radicals.
