Abstract Porcinepancreaticlipase (PPL), pre-incubated with acetophenone in tetrahydrofuran, fails to recognize ortho- and para-acyloxy functions with respect to the nuclear carbonyl group in (±)-2,4-diacyloxyphenyl alkyl ketones and produces novel aryl alkyl ketones in moderate-to-highly optically active forms; this result supports the hypothesis on the mechanism of action of PPL in deacylation reactions
