A practical synthesis of the bicyclic dienyl sultam I has been developed. The viable route involved several key steps. Of these, ring-closing metathesis, represented by the conversion of II to III, had to be implemented in advance of the assembly of other rings such as is present in IV. The second double bond was best introduced by a bromination-dehydrobromination sequence, the 2-fold loss of HBr being achieved most reliably by the use of tetra-n-butylammonium fluoride in CH2Cl2 or DMSO. The direct irradiation of I gave rise to the endo-oriented cyclobutene derivative V. The title diene is not a ready participant in Diels-Alder reactions. When heated with endo-bornyltriazolinedione in Et acetate solution, conversion to a 1:1 mixture of VI and its diastereomer occurred as confirmed by X-ray crystallog. anal. From the mechanistic perspective, this transformation constitutes an interesting example of a stereocontrolled and regioselective [2+2] cycloaddition followed by a vinylcyclobutane-cyclohexene rearrangement. Products V and VI constitute examples of strained sulfonamides featuring a norbornyl-like structural component.
