The enantioselective resolution of quaternary alpha-acetoxy alpha-substituted indanone and 1-tetralone derivatives was performed with commercially available enzyme CRL in pH = 8.0 phosphate buffer. Various parameters that would affect the enantoselectivities were tested, and the optimal enzymatic resolution condition was found to afford the enantiomerically enriched quaternary acetoxylated substrates with high ees (varied between 81% and 85%).
