Chiral Definition & Meaning - Merriam-Webster

WebEnantioselective synthesis, also called asymmetric synthesis, is a form of chemical synthesis.It is defined by IUPAC as "a chemical reaction (or reaction sequence) in which one or more new elements of chirality are formed in a substrate molecule and which produces the stereoisomeric (enantiomeric or diastereomeric) products in unequal amounts.". Put … WebJul 3, 2024 · Chiral Center Definition. A chiral center is defined as an atom in a molecule that is bonded to four different chemical species, allowing for optical isomerism.
