Abstract
Both enantiomers of endo-9-hydroxy-7-oxabicyclo[4.3.0]non-4-en-8-one ( +)-(3) and(-)-(3) as well as 1R,6R,9R)-9-hydroxy-7-oxabicyclo[4.3.0]no n-4-en-8- one (+)-(4) have been obtained in states of high optical pur ity by kinetic resolutions involving enzyme-catalysed hydrolyses. Abso lute configurations were assigned by chemical interconversions and by X-ray crystallography on Mosher's ester(+)-(7).
