First synthesis of sporothriolide (1) and 4--ethisolide (2) is described, where the crucial bicyclo[3.3.0]octane systems 3 and 4 have been made by the adoption of regio- and stereoselective intramolecular radical cyclisation reaction onto the ‘chirons’ derived from ‘diacetoneglucose’.

The biosynthetic gene cluster of the antifungal metabolite sporothriolide 1 was identified from three producing ascomycetes: Hypomontagnella monticulosa MUCL 54604, H. spongiphila CLL 205 and H. submonticulosa DAOMC 242471. A transformation protocol was established, and genes encoding a fatty acid synthase subunit and a citrate synthase were simultaneously knocked out which led to loss of sporothriolide

Two new thioether specialised metabolites isolated from the fungus Hypomontagnella monticulosa show attenuated antifungal properties, but retain biofilm inhibition activity.
An enantioselective total synthesis of sporothriolide, a bioactive furofurandione-type fungal metabolite, has been achieved in a 21% overall yield from a commercially available β,γ-unsaturated carboxylic acid via seven steps. The key steps of this synthesis include a highly diastereoselective Michaeladdition of a chiral oxazolidinone derivative to a nitro olefin, the exploitation of an aromatic ring
