Keto-enol tautomerism referred to the chemical equilibrium between the keto and enol form established by the alloxan-like structure as described on the left-hand and right-hand side, respectively.Ilen...
Enzymatic conversion of dihydrotestosterone from 3-keto to 3-enol form in the rat prostate. 来自 Semantic Scholar 喜欢 0 阅读量: 15 作者:D Kouretas,S Voyatzi,D Sahpazidou,K Lazopoulos,O Antonoglou 摘要: Dihydrotestosterone (DHT) is the active androgen, as well as a strong tumor promoter...
Theβ-ketoamine COFs, formed by reversible Schiff base reaction and irreversible enol-to-keto tautomerization, are a huge and representative category of highly stable COFs. In this work, we designed a series ofβ-ketoamine COFs with the same topology and similar atomic composition as a model sy...
The trans-isomer gives the diethylphosphoric ester of the enol form of the ester of cyclohexanone-2-phosphonic-1 acid as the main reaction product. With the cis-form the diethyl ester of cyclohexanone-2-phosphonic-1 acid is formed. In both cases, the products enumerated in paragraph 1 also ...
(1980) disclose fluoride ion catalyzed O-acylation of silyl enol ethers with compounds of the type RXC(O)F where X is O, NR' or a single bond, R is a cyclic or acyclic aliphatic radical and R' is methyl or, together with R, morpholino. C-acylation of silyl enol ethers is not ...
The interaction of diketo and keto-enol form of thymine and uracil tautomers with acridine (Acr), phenazine (Phen), benzo[c]cinnoline (Ben), 1,10-phenanthroline (1,10-Phe), and 4,7-phenenthroline (4,7-Phe) intercalating drug molecules was studied using density functional theory at ...

(57) aryl according to the summary of the present invention - keto - has formula (I), enol form heterocyclic compound, a heterocyclic group, the group (a), (b) or (c) to the formula Het have the meanings described in the specification X, Y, Z, n, A, B, E, and M to L, ...
It has been shown that the enol tautomer of quercetin is more stable in aqueous solutions, while the ketone form is stabilized in miramistin-containing media. The apparent dissociation constants have been determined for the enol (p K a a = 6.60) and ketone = 5.64) tautomeric forms of ...
The Keto–Enol Tautomerism of Biliverdin in Bacteriophytochrome: Could it Explain the Bathochromic Shift in the Pfr Form?Phytochromes are ubiquitous photoreceptors found in plants, eukaryotic algae, bacteria, and fungi. Particularly, when bacteriophytochrome is irradiated with light, a Z‐to〦 (photo...
