(±)-Bicyclo [3.2.0] hept-2-en-6-one (1) was reduced using a variety of fungi and yeasts. Bakers' yeast gave 6-exo-(1R,5S,6S)-bicyclo [3.2.0] hept-2-en-6-ol (2a) and 6-endo-(1S,5R,6S)-bicyclo[3.2.0]-hept-2-en-6-ol (3b) while Curvularia lunata and Mortierella ramanniana gave only the 6-endo-alcohol (3b) and optically active bicycloheptenone (1a). Under slightly modified reaction conditions (±)-6-endo-bicyclo
bicyclo[3.2.0]hept-3-en-6-ones (1a−f) have been converted into the corresponding bicyclo[3.2.0]heptane-2-endo,7-endo-diols (4a−f) in an efficient and stereoselective fashion. This preparation opens a route to a family of 1,3-diols with a chiral rigid backbone, potentially suitable as nonracemic precursors for bidentate ligands in asymmetric synthesis.
