Biotransformations in the regioselective deacetylation of polyphenolic peracetates in organic solvents.
Regioselectivity has been observed in the deacetylation of peracetates of polyphenolic aromatic ketones by lipases from porcine pancreas (PPL) and Candida cyclindracea (CCL) suspended in organic solvents. The deacetylation of acetoxyl groups at positions para and meta to the carbonyl (ketonic) group is favoured over the one at the ortho position.
