5Enantioselective synthesis — Enantioselective synthesis: Sharpless epoxidation Enantioselective synthesis, also called chiral synthesis, asymmetric synthesis or stereoselective synthesis, is organic synthesis that introduces one or more new and desired elements of… …
6Asymmetric synthesis — Asymmetric synthesis, also called chiral synthesis, enantioselective synthesis or stereoselective synthesis, is organic synthesis which introduces one or more new and desired elements of chirality. [GoldBookRef|title=asymmetric synthesis| file =… …
7isomerism — /uy som euh riz euhm/, n. 1. Chem. the relation of two or more compounds, radicals, or ions that are composed of the same kinds and numbers of atoms but differ from each other in structural arrangement (structural isomerism), as CH3OCH3 and… …
8Diastereomeric recrystallization — is a method of chiral resolution of enantiomers from a racemic mixture. It differs from asymmetric synthesis, which aims to produce a single enantiomer from the beginning, in that diastereomeric recrystallization separates two enantiomers that… …
9Stereoisomerism — The different types of isomers. Stereochemistry focuses on stereoisomers Stereoisomers are isomeric molecules that have the same molecular formula and sequence of bonded atoms (constitution), but that differ only in the three dimensional… …
10Topicity — Main article: stereochemistry In chemistry, topicity is the stereochemical relationship of substituents relative to the structure to which they are attached. Depending on the relationship, such groups can be heterotopic, homotopic, enantiotopic,… …
