Visible Light-Mediated [2 + 2] Cycloaddition Reactions of 1,4-Quinones and Terminal Alkynes

A single-step synthesis of 4-hydroxy-functionalized bi-aryl and aryl/alkyl ketones via oxidative coupling of terminal alkynes with benzoquinones is reported. Furthermore, with naphthoquinones, owing to the cross-resonance of carbonyl with the aromatic ring, alkene-alkyne cycloaddition is more favored to give four-membered carbocyclic adducts, thereby precluding the requirement of preactivated alkynes.

Synthesis and biological evaluation of novel 4-hydroxytamoxifen analogs as estrogen-related receptor gamma inverse agonists

Estrogen-related receptor gamma (ERRγ) has recently been recognized as an attractive target for treating inflammation, cancer, and metabolic disorders. Herein, we discovered and demonstrated the in vitro pharmacology as well as the absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties of chemical entities that could act as highly selective inverse agonists for ERRγ. The results were comparable to those for GSK5182 (4), a leading ERRγ inverse agonist ligand. Briefly, the half-maximal inhibitory concentration (IC50) range of the synthesized compounds for ERRγ was 0.1-10 μM. Impressively, compound 24e exhibited potency comparable to 4 but was more selective for ERRγ over three other subtypes: ERRα, ERRβ, and estrogen receptor α. Furthermore, compound 24e exhibited a superior in vitro ADMET profile compared to the other compounds. Thus, the newly synthesized class of ERRγ inverse agonists could be lead candidates for developing clinical therapies for ERRγ-related disorders.

Tandem catalysis: Access to ketones from aldehydes and arylboronic acids via rhodium-catalyzed addition/oxidation

Direct cross-coupling reactions of aromatic aldehydes with arylboronic acids afforded ketones in high yields and under mild conditions in the presence of a rhodium catalyst, acetone and a base. This new reaction, involving a formal aldehyde C-H bond activation, is believed to proceed via a tandem process involving addition of the organometallic species to the aldehyde followed by oxidation by β-hydride transfer.

4-(2-[2-(2(R)-Methylpyrrolidin-1-yl)ethyl]benzofuran-5-yl)benzonitrile and related 2-aminoethylbenzofuran H3 receptor antagonists potently enhance cognition and attention

H3 receptor antagonists based on a 2-aminoethylbenzofuran skeleton have been discovered, which are potent in vitro at human and rat H 3 receptors, with Ki values of 0.1-5.8 nM. Analogues were discovered with potent (0.01-1 mg/kg) cognition and attention enhancing properties in animal models. One compound in particular, 4-(2-[2-(2(R)- methylpyrrolidin-1-yl)ethyl]benzofuran-5-yl)benzonitrile (ABT-239), combined potent and selective H3 receptor antagonism and excellent pharmacokinetic and metabolic properties across species, with full efficacy in two behavioral models: a five-trial inhibitory avoidance acquisition model in rat pups at 0.1 mg/kg and a social recognition memory model in adult rats at 0.01 mg/kg. Furthermore, this compound did not stimulate locomotor activity and showed high selectivity for the induction of behavioral efficacy versus central nervous system based side effects. The potency and selectivity of this compound and of analogues from this class support the potential of H3 receptor antagonists for the treatment of cognitive dysfunction.

Synthesis and structure-activity studies of novel orally active non-terpenoic 2,3-oxidosqualene cyclase inhibitors

New orally active non-terpenoic inhibitors of human 2,3-oxidosqualene cyclase (hOSC) are reported. The starting point for the optimization process was a set of compounds derived from a fungicide project, which in addition to showing high affinity for OSC from Candida albicans showed also high affinity for human OSC. Common structural elements of these inhibitors are an amine residue and an electrophilic carbonyl C atom embedded in a benzophenone system, which are at a distance of about 10.7 ?. Considering that the keto moiety is in a potentially labile position, modifications of the substitution pattern at the benzophenone as well as annelated heteroaryl systems were explored. Our approach combined testing of the compounds first for increased binding affinity and for increased stability in vitro. Most promising compounds were then evaluated for their efficacy in lowering plasma total cholesterol (TC) and plasma low-density lipoprotein cholesterol (LDL-C) in hyperlipidemic hamsters. In this respect, the most promising compounds are the benzophenone derivative 1·fumarate and the benzo[d]-isothiazol 24·fumarate, which lowered TC by 40% and 33%, respectively.

Synthesis and structure-activity relationships of benzophenone hydrazone derivatives with insecticidal activity

A broad range of benzophenone hydrazone derivatives was prepared and tested against selected chewing insect pests, allowing the analysis of structure-activity relationships. Good activity was found only when the aromatic rings were substituted at the 4-positions with an halogen atom and a triflate or perhaloalkoxy group. In contrast, a number of substituents on the hydrazone part led to active compounds, the best results being achieved with acyl-type substituents. The excellent laboratory and greenhouse activity of the best representatives was confirmed in semi-field trials against Spodoptera littoralis. ° 2001 Society of Chemical Industry.

Polymerisation and Related Reactions involving Nucleophilic Aromatic Substitution. Part 1. The Rates of Reaction of Substituted 4-Halogenobenzophenones with the Potassium Salts of Substituted 4-Hydroxybenzophenones

The rate of displacement of fluorine from 4'-X,4-fluorobenzophenones by the potassium salts of 4'-X,4-hydroxybenzophenones (X = CF3, Cl, F, H, OPh, and OMe) has been studied at 175-225 deg C in diphenyl sulphone as solvent.Comparison with the corresponding rate of displacement of chlorine indicates that the reaction is a bimolecular nucleophilic aromatic substitution.The reaction obeys the Hammett equation using normal ? values for substitution in both the substrate (ρ 1.19) and the phenolate (ρ -0.53).There is also a marked salt effect on the reaction rate and this has been included with the substituent constants in a general equation for the calculation of rate coefficients.The effect of an O- substituent is more marked than would have been expected from the previous range of ? values ascribed to this substituent.

Chemical process

Preparation of para-substituted 4-hydroxybenzophenones by reacting appropriately substituted aromatic compound with poly(4-oxybenzoyl) in the presence of an acid catalyst. The reaction with the appropriately substituted aromatic compound, for example fluorobenzene, is effected in the presence of an acid catalyst such as a strong proton acid or a Lewis Acid or a mixture thereof.

Production of hydroxy arylophenones

Production of a hydroxy arylophenone by reacting an aromatic carboxylic acid Ar(--CO2 H)p where Ar is an aromatic radical, (--CO2 H) is an aromatic carboxylic acid group, and p is 1 or 2 with an aromatic compound H--Ar'--OH where Ar' is an aromatic radical and --H and --OH are aromatically bound para to each other in a benzenoid ring, in the presence of an alkyl sulphonic acid, particularly methane sulphonic acid, to produce a hydroxy arylophenone of formula Ar(--CO--Ar'--OH)p where the carbonyl and hydroxyl groups are para to each other in the hydroxyl-containing benzenoid ring of Ar'. The production of the hydroxy arylophenone proceeds through the intermediate ester (H--Ar'--O--CO--)p Ar and the production of the hydroxy arylophenone starting from the ester is also claimed.
