Twenty-three lipases were subjected to an evaluation of selectivities in transesterification of 2 with vinyl acetate in hexane (Eq. 1). Results are summarized in Table 1. Most lipases (including a further 13 lipases which are not listed in Table 1) react selectively with the (R)-enantiomer while three lipases (LIP, LPL and OF) prefer to react with the (S)-enantiomer. Three lipases (Amano AK, AH and PS) were selected and employed for further studies, because they ...
