One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, name: 6-Methoxybenzofuran, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 50551-63-8, Name is 6-Methoxybenzofuran, molecular formula is C9H8O2

An efficient and environmentally benign heterogeneous catalytic process for the synthesis of 2,3-unsubstituted benzo[b]furans has been established via the intramolecular cyclization of 2-aryloxyacetaldehyde acetals. By utilizing tin-exchanged H-beta zeolite (Sn-beta) as catalyst, a wide range of functionalized 2,3-unsubstituted benzo[b]furans could be prepared in good to excellent yields. The Sn-beta zeolite catalyst also exhibited excellent shape selectivity on the cyclization of meta-substituted 2-aryloxyacetaldehyde acetals, and 6-substituted isomers were preferably formed up to 97% regio-selectivity. Moreover, Sn-beta zeolite could be easily recovered and reused without any noticeable activity loss.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. name: 6-Methoxybenzofuran, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 50551-63-8, in my other articles.

Electric Literature of 67713-99-9, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 67713-99-9, Name is 3-(Chloromethyl)benzofuran,introducing its new discovery.

Acrylic acids and alanines substituted with heteroaryl groups at the beta-position were synthesized and spectroscopically characterized (UV, HRMS, 1H NMR, and 13C NMR spectroscopy). The heteroaryl groups were furanyl, thiophenyl, benzofuranyl, and benzothiophenyl and contained the alanyl side chains either at the 2- or 3-positions. While the former are good substrates for phenylalanine ammonia lyase (PAL), the latter compounds are inhibitors. Exceptions are thiophen-3-yl-alanine, a moderate substrate and furan-3-yl-alanine, which is inert. Possible reasons for these exceptions are discussed. Starting from racemic het eroaryl-2-alanines their D-enantiomers were prepared by using a stereodestructive procedure. From the heteroaryl-2- acrylates, the L-enantiomers of the heteroaryl-2-alanines were prepared at high ammonia concentration. These results can be best explained by a Friedel – Crafts-type electrophilic attack at the aromatic part of the substrates as the initial step of the PAL reaction.

A series of new ecteinascidin pentacyclic-derived compounds bearing aryl carboxylic amide side chains at C-22 have been designed and synthesized. The cytotoxicity evaluation confirmed their potent antitumor activity by use of eight different cell lines. Studies on the structure-activity relationship of them showed that the chemical structure of C-22 pendants have great effects on the tumor-killing activity. Notably, Compounds 6, 7 and 8 with benzo[b]thiophene-2-carboxamide pendants exhibited excellent broad-spectrum antitumor activity with the low IC50 values of 10?7 M.

Benzoxazinediones exhibit potential as versatile synthons in the synthesis of wide variety of heterocyclic compounds with biological activity. In this work, an efficient and eco-friendly onestep synthesis of benzoxazine-2,4-diones from phthalic anhydrides derivatives and trimethylsilyl azide using the microwave technique was developed and compared with conventional heating. Microwave irradiation plays a critical role in driving the reaction and providing access to products and/or regioisomers not available from conventional heating. Thus, the regioselectivity of the reaction may be modulated by the irradiation time. Depending on the method employed the benzoxazinediones were isolated with yields in the range of 30?90%. (image presented).

Three model compounds required for an approach to thebaine by intramolecular [4+2] cycloaddition were prepared. In the first two cases the anticipated cycloaddition products were obtained under thermal conditions. Thermolysis of the third, more advanced model compound, afforded products resulting from rearrangements and/or elimination. A study of analogous intra- and intermolecular reactions using benzofuran as dienophile and various electron-poor and electron-rich dienes (pyridazines, pyranones, Danishefsky diene) was undertaken.
