Abstract

A series of arylalkylcarbinol derivatives were deracemized through sequential combination of Candida antarctica lipase B (CAL-B) catalyzed resolution by hydrolysis and Mitsunobu stereoinversion. The (S)-acetates were obtained in 71%–99% ee and 76%–89% yields. An enantiocomplementarity was established for the hydrolysis and acylation reactions with CAL-B lipase. Thus, the (S) and (R) enantiomers of Indan-1-yl acetate, 1,2,3,4-tetrahydro-1-naphthalenol acetate and 1-(2-naphthyl) ethyl acetate were obtained in 91%–99% ee and 76%–89% yield.
Keywords: deracemisation; lipase; hydrolysis; stereoinversion; arylalkylcarbinol deracemisation; lipase; hydrolysis; stereoinversion; arylalkylcarbinol
