The antifungal mold metabolites isoavenaciolide (1b) and avenaciolide (1c) have been synthesized in racemic form from a common precursor, α-methylene lactone 4, obtained via a glycolate ester enolate Claisen rearrangement.

of natural products are small α-methylene bis-γ-lactones that exhibit a wide variety of biological activities. Herein we report concise syntheses of five members of this family of natural products along with the synthesis of one non-natural analogue. The syntheses proceed in five or six steps from simple, commercially available compounds and feature a key oxidative cyclization/lactonization reaction
A short totalsynthesis of (±)-ethisolide and (±)-isoavenaciolide was accomplished from (±)-oxanorbornenone respectively in 11 and 12 steps, using a radicalcyclization as a keystep.
Stereo-divergent asymmetric total synthesis of avenaciolide and isoavenaciolide. Complete reversal of stereoselectivity in reduction of 2-vinyl aldols with / without trimethylsilyl directing group
Stereo-divergent: asymmetric total synthesis of avenaciolide and isoavenaciolide was achieved via 1,2-rearrangement of chiral epoxyalcohol derivatives, where complete reversal of stereoselectivity with / without the TMS-directing group in the reduction of 2-vinyl aldols was used as the key branching point.
