Asymmetric synthesis; the essentials.9783527313990 Asymmetric synthesis asymmetric synthesis Chemical reaction by which unequal amounts of two product isomers are formed. It is normally not possible to synthesize from materials that do not have optical activity (i.e. ; the essentials. Ed. by Mathias Christmann and Stefan Brase. Wiley-VCH 2007 345 pages $115.00 Paperback QD415 Christmann (PhD, chemistry, U. of Hannover, Germany) and Brase (organic chemistry, Technical U. of Karlsruhe, Germany) present 58 essays describing applications and methods in asymmetric synthesis, the intentional construction of enantiomers enantiomers (i·nanˑ·tē·  ·merz),n. of a given constitutional isomer isomer (ī`səmər), in chemistry, one of two or more compounds having the same molecular formula but different structures (arrangements of atoms in the molecule). Isomerism is the occurrence of such compounds. by means of chemical reaction. They have arranged the papers into five sections dealing with the creation of new stereocenters using existing stereochemical information in the molecule or from a chiral auxiliary A chiral auxiliary is a chemical compound or unit that is temporarily incorporated into an organic synthesis so that it can be carried out asymmetrically with the selective formation of one of two enantiomers [1] [2] . , metal-catalyzed asymmetric synthesis, asymmetric catalysis catalysis Modification (usually acceleration) of a chemical reaction rate by addition of a catalyst, which combines with the reactants but is ultimately regenerated so that its amount remains unchanged and the chemical equilibrium of the conditions of the reaction is not with enzymes and small organic molecules, asymmetric reactions in total synthesis, and asymmetric synthesis for the production of drugs and fine chemicals.
