Two new synthetic approaches to anhydrogabosines are developed from the polyoxygenated aldol cyclization intermediates, bearing different O-protecting groups, which were transformed to various gabosine-type cyclitols. Selective sulfonylation on the required hydroxyl group of the intermediates and the subsequent oxirane ring closure are employed as the key steps in both approaches, by which (+)-epoxydon, (–)-phyllostine, (–)-RKTS 33, and (–)-parasitenone were synthesized from δ-d-gluconolactone.
Enantioselective total synthesis of epoxyquinone natural products (-)-phyllostine, (+)-epoxydon, (+)-epiepoxydon and (-)-panepophenanthrin: Access to versatile chiral building blocks through enzymatic kinetic resolution

A new enzyme mediated protocol to access versatile chiral building blocks for the synthesis of epoxyquinone natural products is delineated. Total syntheses of (-)-phyllostine, (+)-epoxydon, (+)-epiepoxydon and (-)-panepophenanthrin have been accomplished to demonstrate the efficacy of this approach.

(±)-epi-Epoxydon was synthesised by means of a triethylaluminium/tri-n-butylphosphine-catalysed Baylis-Hillman reaction between an O-protected epoxidised hydroxyquinol core and paraformaldehyde, constituting the first application of the Baylis-Hillman reaction to a highly functionalised β-substituted enone.
