Interleukin-1 and tumor necrosis factors-α modulators, syntheses of said modulators and methods of using modulators

Novel compounds are disclosed that have the chemical structure of Formula (IIB), and its prodrug esters and acid-addition salts, and that are useful as Interleukin-1 and Tumor Necrosis Factor-α modulators, and thus are useful in the treatment of various d

Enantioselective synthesis of the antiinflammatory agent (-)-acanthoic acid

An enantioselective synthesis of the potent antiinflammatory agent (-)-acanthoic acid (1) is described. The successful strategy departs from (-)-Wieland-Miescher ketone (10), which is readily available in both enantiomeric forms and constitutes the starting point toward a fully functionalized AB ring system of 1. Conditions were developed for a regioselective double alkylation at the C4 center of the A ring, which produced compound 32 as a single stereoisomer. Construction of the C ring of 1 was accomplished via a Diels-Alder reaction between sulfur-containing diene 43 and methacrolein (36), which after desulfurization and further functionalization yielded synthetic acanthoic acid. The described synthesis confirms the proposed stereochemistry of the natural product and represents a fully stereocontrolled entry into an underexplored class of biologically active diterpenes.
