Asymmetric chemical synthesis is extremely important because it allows chemists to produce new chiral drug candidates, such as
single enantiomers of nonnaturally occurring amino acids.
The majority of naturally occurring (plant and animal) substances for which stereoisomers are possible exist in nature as
single enantiomers.
Regarding my particular interests in organic synthesis, we always have to deal with chiral molecules which are present in nature as
single enantiomers.
When derivatives were resolved in
single enantiomers, compounds with S - configuration at the chiral center showed higher CXCR4 antagonistic activity with respect to the corresponding R - isomers.
