Synthesis and Absolute Configuration of Natural 2-Pyrones

2-Pyrones are frequently produced by microorganisms and often exhibit interesting bioactivities. Therefore, a short and easy synthetic access to these natural products is desirable. Synthetic routes to nectriapyrone, gibepyrone A, racemic gulypyrone A, (+)-germicidin C, (ent)-desoxygermicidin C and (ent)-prolipyrone A via a modular approach are presented, allowing the assignment of the absolute configurations of the latter three chiral compounds. The method failed for the synthesis of (ent)-phomapyrone B that was thus synthesized via a different route, resulting in an assignment of the absolute configuration of natural phomapyrone B.
Advances and Setbacks in the Total Synthesis of the Fungal Metabolite Curvicollide C: Synthesis and Elaboration of Non-Aldol Stereotriads from Gosteli-Type Allyl Vinyl Ethers

Advances and setbacks are reported in regard to the asymmetric total synthesis of the fungal metabolite curvicollide C relying on a synthetic strategy that exploits non-aldol stereotriads as chiral building blocks. A catalytic asymmetric Gosteli-Claisen rearrangement, a two-step aldehyde-to-alkyne-homologation, and a Julia-Kocienski olefination served as key C/C-connecting transformations.

Anaerobic growth of the bacterium strain HxN1 with n-hexane gives nearly equal amounts of (2R,1 R)- and (2S,1 R)-(1-methylpentyl)succinate, which are formed by the radical addition of the hydrocarbon to fumarate (see scheme). The highly selective attack on the pro-S hydrogen atom at C2 of n-hexane is associated with inversion of the configuration at C2 during binding to fumarate and exhibits isotopic discrimination against a C-2H bond.
