Abstract
Enantioselective deacetylation of -(±)-botryodiplodin acetate was successfully accomplished by means of Lipase PS to afford -(+)-botryodiplodin and -(+)-botryodiplodin acetate with high enantiomeric excesses. Enzyme-mediated transesterification of the acetylated molecule with n-butanol as well as its hydrolysis in several organic solvents are also reported. The CD spectra of -(+)-botryodiplodin and -(+)-botryodiplodin acetate are also presented.
