The crystal structure and FTIR spectrum of 3-formylchromone (0) have been analysed. A new organic ligands, 3-(anilinomethylene)-2-methoxychroman-4-one (1) and 3-(1?,4?-benzodioxan-6?-aminomethylene)-2-methoxychroman- 4-one (2) were synthesized. The products of reactions between 3-formylchromone and aniline and 6-amino-1,4,-benzodioxane were studied by elemental analysis, FTIR spectroscopy, thermal analysis and X-ray crystallography. It has been found that these reactions allow to obtain derivatives of 4-chromanones from 3-formylchromone by the mechanism of nucleophilic addition, accompanied by the opening of the pyrone ring. The experimental results indicate that compounds (1) and (2) are thermal stable up to 90 and 100 C, respectively. The FTIR spectra and X-ray analysis showed the present of methoxy-group in these compounds.

Homocamptothecins (hCPTs) represent a class of new emerging antitumor agents, which contains a seven-membered beta-hydroxylactone in place of the conventional six-membered alpha-hydroxylactone ring (E ring) of camptothecins. Some novel 7-substituted hCPTs were designed and synthesized based on a newly developed synthetic route which couples ring A with ring C, E and D. Most of the synthesized compounds exhibit very high cytotoxic activity on tumor cell line A549. Some compounds, such as 9b, 9l, and 9y, show broad in vitro antitumor spectrum and are more potent than topotecan. Three-dimensional quantitative structure-activity relationship (3D-QSAR) methods, CoMFA and CoMSIA, were applied to explain the structure-activity relationship (SAR) of the synthesized compounds. Furthermore, molecular docking was used to clarify the binding mode of the synthesized compounds to human DNA topoisomerase I. The important hydrophobic, base-pair stacking, and hydrogen-bonding interactions were observed between the hCPT derivatives and their receptor. The results from molecular modeling will guide the design of novel hCPTs with higher antitumor activity.

Facile 4pi conrotatory imino-Nazarov cyclization of a 1-aminopentadienyl cation generated from condensation an aldehyde and secondary aniline in the presence of a catalytic amount of a Lewis acid has been developed. Silver(I)-catalyzed intramolecular arene trapping of the resulting cyclic oxyallyl cation leads to formation of tricyclic indoline-fused cyclopentanone. The use of lanthanide salts allows transformation after the initial trapping to afford tetrahydroquinoline-fused cyclopentenone in a concise manner. Taking control: The fate of an oxyallyl cation formed through a 4pi conrotatory imino-Nazarov cyclization can be controlled to access cyclopentanoid frameworks. In the presence of silver(I), intramolecular arene trapping leads to indoline-fused cyclopentanones. Gadolinium(III) facilitates a cascade transformation to furnish tetrahydroquinoline-fused cyclopentenones. Tf=trifluoromethanesulfonyl.

Methylation of histone arginine residues is an epigenetic mark related to gene expression that is implicated in a variety of biological processes and can be reversed by small-molecule modulators of protein arginine methyltransferases (PRMTs). A series of symmetrical ureas, designed as analogues of the known PRMT1 inhibitor AMI-1 have been synthesized using Pd-catalyzed Ar-N amide bond formation processes or carbonylation reactions as key steps. Their inhibitory profile has been characterized. The enzymatic assays showed a weak effect on PRMT1 and PRMT5 activity for most of the compounds. The acyclic urea that exhibited the strongest effect on the inhibition of the PRMT1 activity also showed the greatest effect on the expression of some androgen receptor target genes (TMPRSS2 and FKBP5), which may be related with its enzymatic activity. Surprisingly, AMI-1 behaved as an activator of PRMT5 activity, a result not reported so far.

Forty-two new disubstituted phenylsulfamates have been synthesized, and 30 of these have been combined with 40 already available from earlier work to create a training database of 70 compounds. On the basis of panel taste data these were divided into three categories, N (nonsweet), N/S (nonsweet/sweet), and (S) sweet, and a “sweetness value” or weighting was also calculated for each compound. Using these 70 compounds as a training set and a series of nine predictors derived from Corey-Pauling-Koltun (CPK) models, calculated from the PC SPARTAN PRO program and Hammett sigma values taken from the literature, a classification and regression tree analysis (CART) was carried out leading to a regression tree that correctly classified 62 of the 70 compounds (89% overall correct classification). The tree’s predictive ability varies for the different taste categories, and for nonsweet compounds it is virtually 100%; for nonsweet/sweet compounds it is 66%, and for sweet compounds it is ?75%. This tree correctly predicted taste categories for 10 compounds from a test set of 12 randomly selected from among the 42 new compounds (83% correct classification). Therefore, it can be used with a good degree of confidence to predict the tastes of disubstituted phenylsulfamates. For the design of new sweeteners, appropriate values or ranges of the descriptors are derived.

The vanilloid receptor-1 (TRPV1 or VR1) is a member of the transient receptor potential (TRP) family of ion channels and plays a role in regulating the function of sensory nerves. A growing body of evidence demonstrates the therapeutic potential of TRPV1 modulators, particularly in the management of pain. As a result of our screening efforts, we identified (E)-3-(4-tert- butylphenyl)-N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acrylamide (1), an antagonist that blocks the capsaicin-induced and pH-induced uptake of 45Ca2+ in TRPV1-expressing Chinese hamster ovary cells with IC50 values of 17 ± 5 and 150 ± 80 nM, respectively. In this report, we describe the synthesis and structure-activity relationship of a series of N-aryl cinnamides, the most potent of which (49a and 49b) exhibit good oral bioavailability in rats (Foral = 39% and 17%, respectively).

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 22013-33-8COA of Formula: C8H9NO2.

The reaction of arylglyoxals, 4-hydroxycoumarin, and aromatic amines such as 7-amino-2-methylchromone, 6/7-aminoflavone, 7-amino-4-methylcoumarin, 1-amino-9-fluorenone, 1-aminoanthraquinone and aniline derivatives in acetic acid medium under microwave conditions provides the corresponding regioselective fused pyrroles having hydroxycoumarin and aryl substituents. Alternatively, we have developed another method using in situ arylglyoxals from acetophenone derivatives by I2/DMSO promoted C-H oxidation followed by one-pot three component cyclization reactions to provide similar fused pyrroles. Using both the methods a series of novel pyrroles fused with pharmacologically important chromone, flavone, coumarin, fluorenone, and anthraquinone moieties were synthesized under metal-free reaction conditions in good to very good yields within a short reaction time. The structures of the synthesized fused pyrroles have been unambiguously confirmed by spectroscopic techniques, mass analysis and single crystal XRD.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 22013-33-8 is helpful to your research. Application In Synthesis of 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine.

Primary aromatic amines are readily converted into arylimino-1,2,3-dithiazoles 2 and the derived cyanothioformanilides 6, both of which are rapidly cleaved by ethylmagnesium bromide in hot THF to give the corresponding isothiocyanates. The transformation 2?6?ArNCS can be performed as a ‘one-pot’ operation. The imines 2 are also converted, more slowly, into the isothiocyanates by sodium hydride in hot THF, via the cyanothioformanilides 6. Conversion of the anilides 6 into isothiocyanates is much faster under microwave irradiation in 2,6-lutidine. Mechanisms are proposed for these reactions.
