Chemo-enzymatic enantio-convergent asymmetric synthesis of (R)-(+)-Marmin

Asymmetric biohydrolysis of trisubstituted terpenoid oxiranes (rac-1a-rac-3a) was accomplished by employing the epoxide hydrolase activity Rhodococcus and Streptomyces spp. Depending on the biocatalyst, the biohydrolysis proceeded in an enantio-convergent fashion and gave the corresponding vic-diols in up to 97% ee at conversions beyond the 50%-threshold. In order to avoid a depletion of the ee of product by further oxidative metabolism, bioconversions had to be conducted in an inert atmosphere with exclusion of molecular oxygen. The synthetic applicability of this method was demonstrated by the asymmetric total synthesis of the monoterpenoid coumarin (R)-(+)-Marmin in 95% ee.

SYNTHESES EN SERIE RACEMIQUE ET EN SERIE OPTIQUEMENT ACTIVE D'UNE FAMILLE DE DERIVES OXYGENES NATURELS DE L'OMBELLIFERONE. STRUCTURE SPATIALE DU (-)EPOXY-3',6' AURAPTENE.

3',6'-Epoxyaurapten and marmin were synthesized by a stereocontrolled way in racemic then in optically active forms from a chiral precursors.The synthetic strategy is of biomimetic type.The reaction sequence involved a Sharpless asymmetric epoxydation as the key-step to induce chirality.E nantiomeric conversion gave rise to the opposite unnatural serie.The structural dimensions of (-)3'6'-epoxyaurapten have been ascertained by means of X-ray cristallography.This route allows the preparation of related molecules.
