The bioconversion of 7-anti-benzyloxymethylbicyclo [2.2.1]hept-5-en-2-one 1 with cells of Acinetobacter calcoaceticus NCIB 9871 has been studied. Its (1R, 4S, 7R) enantiomer underwent a Baeyer-Villiger oxidation yielding rearranged lactone 2 (ee 85%), whereas (1S, 4R, 7S)-1 was reduced to alcohols 3-endo (ee 95%) and 3-exo (o.p. 89%).
