Introduction Many organic substances are chiral molecules, which can exist as levo and dextrorotatory optical antipodes. These molecular entities being mirror images of each other and non-superposable are called enantiomers. 1 In their molecular structures, enantiomers possess a chiral element, which in most cases is a chiral center and less frequently, a …
