Chiral resolution wikipedia
WebResolution of chiral acids through the formation of diastereomeric salts requires adequate supplies of suitable chiral bases. Brucine, strychnine, and quinine frequently are used for this purpose because they are readily available, naturally occurring chiral bases. Simpler … WebKinetic resolution is a very old concept in organic chemistry and can be used in the organic synthesis of chiral molecules. It has been surpassed by other methods. Kinetic resolution was first observed by Marckwald and McKenzie in 1899 [2] in the esterification reaction …
