In organic chemistry, kinetic resolution is a means of differentiating two enantiomers in a racemic mixture. In kinetic resolution, two enantiomers react with different reaction rates in a chemical reaction with a chiral catalyst or reagent, resulting in an enantioenriched sample of the less reactive … Meer weergeven The first reported kinetic resolution was achieved by Louis Pasteur. After reacting aqueous racemic ammonium tartrate with a mold from Penicillium glaucum, he reisolated the remaining tartrate and found it was Meer weergeven With the advent of asymmetric catalysis, it is necessary to consider the practicality of utilizing kinetic resolution for the preparation … Meer weergeven Acylations As with synthetic kinetic resolution procedures, enzymatic acylation kinetic resolutions … Meer weergeven In parallel kinetic resolution (PKR), a racemic mixture reacts to form two non-enantiomeric products, often through completely different reaction pathways. With PKR, … Meer weergeven Kinetic resolution is a possible method for irreversibly differentiating a pair of enantiomers due to (potentially) different activation … Meer weergeven Acylation reactions Gregory Fu and colleagues have developed a methodology utilizing a chiral DMAP analogue to achieve excellent kinetic resolution of secondary alcohols. Initial studies utilizing ether as a solvent, low catalyst … Meer weergeven Dynamic kinetic resolution (DKR) occurs when the starting material racemate is able to epimerize easily, resulting in an essentially racemic starting material mix at all points during the reaction.
