RACEMIC SEPARATION OF 7alpha-ACYLOXY-6beta-HYDROXYMETHYL-2-OXABICYCLO[3.3.0]OCTANE-3-ONES BY STEREO-SPECIFIC ENZYMATIC ACYLATE HYDROLYSIS |
| abstract |
Process for the manufacture of (-)-oxabicyclo[3.3.0]octanolones of formula (-)-I, where R is hydrogen or the residue (a), in which R1 has the notation of a hydrogen, alkyl with 1-7 C atoms, or phenyl. The process is characterized in that a racemic oxabicyclo[3.3.0]-octanolone-acylate of formula (U)-II, where R1 has the above notation, is subjected to a stereo-specific acylate hydrolysis and the (-)-I (R = (a)) is separated from the saponified (+)-I (R = H) or the saponified (-)-I (R = H) is separated from the unsaponified (+)-II. |
