The synthesis of racemic Δ12,14-15-deoxy-PG-J1 is readily achieved in six steps employing as the key transformation a one-pot conjugate addition–Peterson olefination sequence using exo-2-trimethylsilyl-3a,4,7,7a-tetrahydro-4,7-methanoinden-1-one. Additionally a Noyori-type three-componentcoupling approach is employed for the synthesis of enantioenriched epi-Δ12-15-deoxy-PG-J1 from 4(S)-tert-butyl

dienophiles derived from macrocyclic epoxy ketones produce fused ring systems having central cycloheptane subunits. In some cases, the base directly induced cycloisomerization of the epoxy ketones to yield the cycloadducts; in others, the epoxy ketones were transformed into their corresponding enolsilanes before undergoing cycloaddition. Enantiomerically enriched tricyclic arrays were obtained from cycloadditions

A substantial number of sulfobetaines (e.g., 10) have been synthesized and evaluated as inhibitors of squalenesynthase (SS) on the basis of the idea that their zwitterionic structure would have properties conducive both to binding in the active site and to passage through cell membranes. When the simple sulfobetaine moiety is incorporated into compounds containing hydrophobic portions like those in
