WebMay 1, 1992 · The stereoisomeric composition of a drug with a chiral center should be known and the quantitative isomeric composition of the material used in pharmacologic, toxicologic, and clinical studies... WebAmino acids with more than one chiral center are separated into all opti¬cal antipodes so as isoleucine, threonine or cystine. The amino acids must usually be deprotected, followed by ester¬ification and acylation using achiral reagents to obtain volatile derivatives for the chiral separation. The cleav¬age is performed either during ...
