Rhodium catalyzed allene amination: diastereoselective synthesis of aminocyclopropanes via a 2-amidoallylcation intermediate.
The interaction of a sulfamate ester derived metallonitrene with an allene generates a versatile intermediate with 2-amidoallylcation-like reactivity, capable of rearranging to give highly substituted iminocyclopropanes or acting as a novel dipolar species engaging external dipolarophiles.
