Chiral resolution wikipedia
Chiral resolution, or enantiomeric resolution, is a process in stereochemistry for the separation of racemic compounds into their enantiomers. It is an important tool in the production of optically active compounds, including drugs. Another term with the same meaning is optical resolution. The use of chiral resolution to … See more The most common method for chiral resolution involves conversion of the racemic mixture to a pair of diastereomeric derivatives by reacting them with chiral derivatizing agents, also known as chiral resolving agents. … See more • In chiral column chromatography the stationary phase is made chiral with similar resolving agents as described above. See more Via the process known as spontaneous resolution, 5-10% of all racemates are known to crystallize as mixtures of enantiopure crystals. Louis Pasteur exploited this phenomenon by the manual separation of left-handed and right-handed sodium ammonium tartrate See more WebThe advances and recent applications will be presented in detail, in which the contents may bring more thinking to wide-ranging readers in various professional fields, from analytical chemistry, pharmaceutical chemistry, natural medicinal chemistry, to manufacturing of …
