Enol - Wikipedia
Ribulose-1,5-bisphosphate is a key substrate in the Calvin cycle of photosynthesis. In the Calvin cycle, the ribulose equilibrates with the enediol, which then binds carbon dioxide. The same enediol is also susceptible to attack by oxygen (O 2) in the (undesirable) process called photorespiration.

Synthesis of enol phosphates directly from ketones via a modified …
Diversity of enol phosphates, as well as enol phosphonates, enol phosphinates, and enol phosphoramidates were synthesized in high yields directly from the ubiquitously available ketones instead of the unfavourable α-chloroketones under a mild and environmental friendly condition.
由 β -酮酯和亚磷酸酯快速、实用和有效地合成烯醇酯
Abstract: A useful strategy for the synthesis of enol phosphates from β-keto esters via Atherton-Atodd reaction was developed. A variety of enol phosphates can be quickly and readily prepared with broad substrate scope and moderate yields under mild conditions.
Regio- and Stereoselective Synthesis of Enol Carboxylate, Phosphate …
2021年12月28日 · β-Iodo(III)enol carboxylates, phosphates, and tosylates can be efficiently synthesized through regio- and stereoselective iodo(III)functionalization of alkynes. The combination of chlorobenziodoxole and silver salt has proven to generate a versatile cationic iodine(III) electrophile to activate alkynes and engage various carboxylic acids ...

2012年7月29日 · We herein report a metal‐free hydrophosphoryloxylation of ynamides with phosphoric acids, which provides an expeditious route to access useful enol phosphates. The advantages of this protocol include exclusive selectivity, short reaction time, high efficiency, and broad substrate scope.
An efficient synthesis of enol phosphates via organic base …
2012年7月29日 · An inorganic base-promoted domino reaction with organophosphites and acyl cyclopropanes possessing electron-withdrawing substituents is developed and proved to provide an efficient access to functionalized enol phosphates.
Palladium-catalyzed cross coupling of Grignard reagents with in …
2002年9月23日 · With viable conditions in hand for preparing enol phosphates in situ from the corresponding ketones using hindered Grignard reagents, we examined the possibility of a ‘one-pot process’ for converting ketones into alkylated/arylated olefins via …
Enol - an overview | ScienceDirect Topics
Enol (or vinyl) triflates are, in general, more reactive than the corresponding enol phosphate and can readily be replaced by a variety of organometallic reagents and are a particularly attractive source of cycloalkyl electrophiles, being readily and stereospecifically obtained from the corresponding cyclic ketone < 88ACR47 >.
18.1: Enols and Enolates - Chemistry LibreTexts
2023年4月14日 · An enolate is simply a deprotonated enol, which is itself a hydroxyalkene. Enols are in equilibrium with the keto form (preferred), and the enolates themselves have resonance structures that place negative charge on oxygen and carbon, respectively, in …
