The decarboxylative Claisen rearrangement of a range of substituted diallyl 2-sulfonylmalonates is described. The substrates are made by C-carboxylation of the corresponding allyl sulfonylacetates with allyl para-nitrophenyl carbonates. The reactions display a high degree of regioselectivity, with allylic substituents possessing electron-rich substituents at the allyl three-position rearranging preferentially.
