Two approaches to synthesis of functionalized bridged bicyclic sulfonamides with a bridgehead Nitrogen atom were developed. The target compounds were obtained either by introduction of a CH2SO2 bridge into functionalized monocyclic substrates or by finalā€step carboxylation of parent bicyclic cores. The described methods allowed preparation of the final products on a multigram scale.
