Prepared in one step by the method of Craig. Craig, D.; Daniels, K.; MacKenzie, A. R. Tetrahedron 1993, 49, 11263-11304. Lithiation of Z vinyl sulfoxides yields E lithio derivatives; there are conflicting reports on the configurational stability at sulfur in this process; see: (a) Posner, G. H.

The reaction conditions should be strictly controlled to avoid a larger degree of overoxidation of sulfoxide 5a to sulfone 6a in the reaction medium.

note
-
Under these conditions a sulfonyl diene related to 3a gave a more complex mixture of inseparable sulfonyl tetrahydrofurans (62:29:9) in which 6a was the major component. This demonstrates that the sulfinyl functionality plays a crucial role in the observed stereocontrol.

It should be pointed out that phenyl-substituted tetrahydrofuran 5c was produced with diminished selectivity (74:14:12).

For previous syntheses of trans-kumausyne, see: (a) Brown, M. J.; Harrison, T.; Overman, L. E. J. Am. Chem. Soc. 1991, 113, 5378-5384. First total synthesis of (±)-7 in 18 steps from 2-cyclopentylidenecyclopentanone. An optically enriched intermediate (84% ee) was prepared in just one additional step using (S)-O-methylprolinol as chiral controller. (b) Osumi, K.; Sugimura, H. Tetrahedron Lett. 1995, 36, 5789-5792. First enantioselective synthesis of of (-)-7 in 18 steps from L-arabinose; 12 steps are required to lactol 10, our key synthetic intermediate. (c) Martín, T.; Soler, M. A.; Betancort, J. M.; Martín, V. S. J. Org. Chem. 1997, 62, 1570-1571. Total synthesis of (+)-trans-deacetylkumausyne in 22 steps from propargyl alcohol. (d) Lee, E.; Yoo, S.-K.; Cho, Y.-S.; Cheon, H.-S.; Chong, Y. H. Tetrahedron Lett. 1997, 38, 7557-7558. Total synthesis of (-)-7 in 22 steps from D-xylose. (e) When this work was in progress Boukouvalas reported an improved synthesis of (-)-7 in 13 steps: Boukouvalas, J.; Fortier, G.; Radu, I.-I. J. Org. Chem. 1998, 62, 9916-917. This approach produces lactol 10 in seven steps from dimethyl (R)-malate.
