(Z)-ascladiol were prepared following a divergent route from a readily available furan diol. The route toward longianone features an unprecedented TBAF-promoted intramolecular oxa-Michael reaction to a conjugated keto enoate, and the oxidation of dihydrolongianone to longianone with stabilized IBX. The route to isopatulin features a chemoenzymaticsynthesis of (Z)-ascladiol, and the regioselective

A mycotoxin, (E)-ascladiol, was established as a direct precursor of patulin in cell-free preparations of Penicillium urticae patulin-minus mutants J1 and S11, but not S15. Isomerization to a side product, (Z)-ascladiol, was nonenzymatically catalyzed by sulfhydryl compounds.

A new, highly efficient synthesis of neopatulin (1) has been achieved through Lewis acid-catalysed aldol reaction of 2-formyl-1,3-dithiane (4) with 2-(tert-butyldimethylsiloxy)-4-[(tert-butyldimethylsiloxy)-methyl]furan (5).
