Several of these compounds exhibited more potent inhibitory activities than the parent compound I (R = R1 = R2 = H) against the rat passive cutaneous anaphylaxis (PCA) reaction and the enzyme 5-lipoxygenase. Particularly, I (R = 6-Me, R1 = R2 = H) (III) showed an ED50 value of 3.3 mg/kg po in the rat PCA test, which was one-fifth of ketotifen and oxatomide. As compared with ketotifen and oxatomide, III showed a better balance of antiallergic properties due to inhibition of chem. mediator release, inhibition of 5-lipoxygenase, and antagonism of histamine.

Keywords: heterocycle nitrogen diphenylmethyl preparation aromatase inhibition; imidazole diphenylmethyl preparation aromatase inhibitor; pyridine diphenylmethyl preparation aromatase inhibitor. We’ll tell you more about this compound (cas:27469-61-0).

The preparation and in vitro aromatase-inhibitory activity of a wide variety of heterocyclic diphenylmethane derivatives, e.g., (p-ClC4H4)2CRR1 (R = imidazolyl, pyridyl, pyrimidyl, etc.; R1 = H, HO, 1-imidazolyl), are described. Thus (p-ClC4H4)2CHCl was treated with imidazole in DMF containing NaH to give 1-[bis(p-chlorophenyl)methyl]imidazole. The choice of the 2 diaryl-bearing moieties as a vehicle for evaluating the heterocycles was made by comparing a series of imidazole- and pyridine-derived compounds with similar pyrimidine compounds reported previously. A structural model for the most active compounds is also presented. The activity of a related series of compounds containing 2 heterocyclic moieties was consistent with the model. Many of the compounds evaluated, including representatives of the pyridine, imidazole, pyrimidine, pyrazole, triazole, thiazole, and isothiazole classes, exhibit EC50 potencies for aromatase inhibition at low nanomolar levels. These compounds are at least as potent as other nonsteroidal aromatase inhibitors reported previously.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1228185-09-8, is researched, Molecular C27H36Cl2N2, about Synthesis of 4- and 4,5-Functionalized Imidazol-2-ylidenes from a Single 4,5-Unsubstituted Imidazol-2-ylidene, the main research direction is imidazolylidene electrophile nucleophilic addition potassium hexamethyldisilazide intermol rearrangement; unsaturated carbon atom functionalized imidazolylidene derivative preparation.Synthetic Route of C27H36Cl2N2.

Using the nucleophilicity of NHCs and aNHCs, as well as the leaving group ability of the former, the carbon-carbon double bond of imidazol-2-ylidenes can be readily mono- and difunctionalized. Following the addition of electrophiles to the carbene carbon between the nitrogen atoms of the imidazolylidene, the addition of potassium HMDS initiates an intermol. rearrangement leading to products functionalized on the unsaturated carbon atoms. These results provide also a new light on the formation of abnormal carbene adducts from classical unsaturated NHCs.

Flexible application of in synthetic route 97739-46-3

From this literature《Highly ligand-controlled regioselective Pd-catalyzed aminocarbonylation of styrenes with aminophenols》,we know some information about this compound(97739-46-3)Recommanded Product: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane, but this is not all information, there are many literatures related to this compound(97739-46-3).

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane, is researched, Molecular C16H21O3P, CAS is 97739-46-3, about Highly ligand-controlled regioselective Pd-catalyzed aminocarbonylation of styrenes with aminophenols.Recommanded Product: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane.

Achieving chemo- and regioselectivity simultaneously is challenging in organic synthesis. Transition metal-catalyzed reactions are effective in addressing this problem by the diverse ligand effect on the catalyst center. Ligand-controlled regioselective Pd-catalyzed carbonylation of styrenes with aminophenols was realized, chemoselectively affording amides. Using a combination of boronic acid and 5-chlorosalicylic acid as the additives, linear amides were obtained in high yields and selectivity using tris(4-methoxyphenyl)phosphine in acetonitrile, while branched amides were obtained in high yields and selectivity in butanone by changing the ligand to 1,3,5,7-tetramethyl-2,4,8-trioxa-6-phenyl-6-phosphaadamantane. Further studies show that the nature of the ligand is key to the regioselectivity. Cone angle and Tolman electronic parameter (TEP) have been correlated to the reactivity and regioselectivity. Studies on the acid additives show that different acids act as the proton source and the corresponding counterion can help enhance the reactivity and selectivity.
