What does DKR mean in PHYSICS
Dynamic Kinetic Resolution (DKR) is a process used in organic synthesis where one enantiomer of a racemic compound undergoes chemical resolution to form two separate enantiomers. DKR can be used for the preparative synthesis of compounds with optically pure, single enantiomers.

Essential Questions and Answers on Dynamic Kinetic Resolution in "SCIENCE»PHYSICS"
What is Dynamic Kinetic Resolution?
Dynamic Kinetic Resolution (DKR) is a process used in organic synthesis where one enantiomer of a racemic compound undergoes chemical resolution to form two separate enantiomers.
How does Dynamic Kinetic Resolution work?
In DKR, a chiral catalytic agent can selectively bind with one of the two enantiomers present in the mixed substrate, forming an intermediate or complex via an asymmetric reaction. This selective binding can result in preferential formation of the product that binds better with the catalyst over the other.
What are some advantages of Dynamic Kinetic Resolution?
The advantages of DKR include improved yields and selectivity compared to traditional methods such as classical kinetic resolutions and chromatographic separations. It also decreases the number of steps required for typical syntheses, resulting in simpler and more efficient processes.
What type of substrates are suitable for Dynamic Kinetic Resolution?
Substrates suitable for DKR include racemic carboxylic acids and ammonium salts, amines, amino acids, lactones and lactams, alcohols, esters and ethers.
Are there any limitations to using DKR?
There are some limitations associated with using DKR for certain types of substrates due to steric hindrance or reaction conditions only favoring one particular side-reaction pathway over another. Additionally, certain reactive functional groups may interfere with the desired reaction leading to undesired side products or low yields due to competing pathways.
Final Words:
In summary, Dynamic Kinetic Resolution (DKR) is an efficient method that can be used to chemically resolve racemic compounds into their single enantiomer products with improved yield and selectivity compared to traditional methods such as kinetic resolutions or chromatography separations. It has several advantages but there are some limitations related to which substrates it can be applied on and certain reactive functional groups may interfere with the desired reaction pathways.
