enol

[′ē‚nȯl]
(organic chemistry)
An organic compound with a hydroxide group adjacent to a double bond; varies with a ketone form in the effect known as enol-keto tautomerism; an example is the compound CH3COH=CHCO2C2H5.

Also, the oxidation of alkyl enolates using hindered salen-type catalysts with different oxidizing agents has been successfully applied in order to get [alpha]-hydroxy ketones (Fig.
In the area of methodology, the emphasis is on photocycloaddition-fragmentation reactions, new applications of the Diels-Alder reaction, development of synthetically useful phosphorus-containing reagents, chemical reactivity of Ce(III) enolates, and synthetic application of thiol esters.
This volume features a comprehensive treatment of transition metal (palladium, nickel, copper) catalyzed a-arylation of enolates derived from many common functional groups such as ketones, aldehydes, esters and nitriles (Prim, Marque, Gaucher, Campagne) including enantioselective variants; palladium catalyzed cyclization to form indoles (Cacchi, Fabrizi, Goggiamani) one of the most prevalent and important classes of heterocycles in natural products and pharmaceutical agents; and an overview of a newly developed dihydroxylation reaction of alkenes (Donohoe, Bataille, Innocenti) that uses hydrogen bonding interactions to direct the delivery of an osmium catalyst with high selectivity.
