Sharpless epoxidation is a chemical reaction of an allylic alcohol with t-butylperoxide and titanium tetraisopropylate to form an epoxide. To form chiral products it is possible to add diethyltartrates. A chemical reaction is a process involving one, two or more substances (called reactants), characterized by a chemical change and yielding one or more product(s) which are different from the reactants. ... An epoxide is an ether in which the oxygen atom is part of a ring of three or more atoms. ... In chemistry, a molecule is chiral if is not superimposable on its mirror image regardless of how it is contorted. ...

Epoxides can be easily converted into dialcohols, aminoalcohols or ethers, so formation of chiral epoxides is a very important step in the synthesis of natural products. Ether is the general name for a class of chemical compounds which contain an ether group — an oxygen atom connected to two (substituted) alkyl groups. ...
