New methods for the elaboration of sultones enable a short and highly stereoselective synthesis of methyl nonactate and establish vinylsulfonyl chloride as an allene equivalent for the intramolecular Diels-Alder reaction.
Methyl nonactate is available with excellent stereoselectivity in only six ste

Sultones are readily prepared by intramolecular Diels-Alder reaction of vinylsulfonates in an often highly stereoselective fashion. Various methods for the synthetic elaboration of these heterocycles have been developed and applied to the total synthesis of biologically active natural products.
