Enzymatic kinetic resolution
WebNov 1, 2004 · The kinetic resolution occurs when kR ≠ kS and the reaction is stopped somewhere between 0% and 100% conversion. Ideally one enantiomer reacts much faster than the other, for example, if the reactant ( R) is the only reacting enantiomer ( kS = 0). WebSep 15, 2024 · Successful enzymatic kinetic resolutions were possible for all three of the substrates tested, with cinnamaldehyde derivative 5b giving the best overall resolution with a lipase from Pseudomonas fluorescens (Sigma-Aldrich cat. no. 95608) (entry 7) and Amano AK lipase (entry 8).
