title: Novel formation and use of a Nicholas carbocation in the synthesis of highly substituted tetrahydrofurans.
abstract: The first formation of a Nicholas carbocation through cleavage of a carbon-carbon sigma bond has allowed the preparation of highly substituted tetrahydrofurans in a formal dipolar cycloaddition reaction.
