In a document, author is Abdoli, Mahshid.

Spiro-acridine/indoline and indoline derivatives were synthesized by the three-component reaction of isatin, dimedone, and amines or amino acids in the presence of acid-functionalized multiwalled carbon nanotubes/La2O3 (MWCNTs)-COOH/La2O3 hybrid (5 mol%) as a highly efficient catalyst in ethanol. The assigned structure was further established by CHN analysis, NMR, and FTIR spectra. (MWCNTs)-COOH/La2O3 was fabricated by the reaction of functionalized (MWCNTs)-COOH and La(NO3)(3).6H(2)O in acetic acid. Synthesis of La2O3 nanoparticles and their conjugation on the surface of MWCNT have been confirmed by FTIR, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and energy-dispersive X-ray spectroscopy.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 56341-37-8, in my other articles.

Indoline framework is often perpended as a privileged heterocycle present in medicinally valuable compounds of natural and synthetic origin. This review article presents the rational approaches/strategies employed for the design of anticancer indolines along with the structure activity relationship and mechanistic insights revealed in the in-vitro and in-vivo assays. The chemist has always been fascinated towards the indoline ring for the construction of antitumor scaffolds owing to its versatility as evidenced by its existence in scaffolds inducing antiproliferative effects via diverse mechanisms. To the delight of medicinal chemist, the applicability of indoline has also been expanded towards the design of dual inhibitors (multitargeting anticancer agents) as well as PROTACS. Overall, it can be concluded that indoline moiety is a magic bullet and the scaffolds containing this ring are foraying towards detailed preclinical and clinical stage investigations by leaps and bounds.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 59-48-3. Computed Properties of C8H7NO.

14192-26-8, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 14192-26-8 as follows.

To the suspension of methyl 2-oxoindoline-6-carboxylate (50 gm, 0.261 mol) in IPA (350 ml) was added slowly SMO-powder (33.8 gm, 0.626 mol) and stirred for about 15 min. Benzyl chloride (44 g, 0.313 mol) was added after completion of the reaction at a reaction temperature of -5 to -10C for about 5hrs. The reaction mixture was quenched into ice-water (700 ml) and acidified with Cone. HC1 (2.0-2.5 ml). Filtered the reaction mixture, washed with water (2X100 ml) and dried the precipitate to obtain crude product which can be recrystallized from acetonitrile (28 ml) to obtain methyl-3-(hydroxy(phenyl)methylene)-2- oxoindoline-6-carboxylate pure crystalline solid (32 gm) (61%) (HPLC purity >97%). The filtrate was evaporated in vacuum to give unreacted methyl 2-oxoindoline-6-carboxylate. MR: 216-223C; IR (KBr, cm”1): 3178, 1711, 1651; 1H-NMR (400 MHz, DMSO): delta 3.80 (s, 3H), 7.17 (s, 1H), 7.28-7.31 (m, 2H), 7.46-7.50 (m, 3H), 7.72 (d, 2H, J = 6.0 Hz), 9.52 (s, 1H), 11.53 (s, 1H); 13C-NMR (100 MHz, DMSO): delta 22.12, 52.41, 101.13, 111.13, 119.23, 123.06, 126.65, 127.06, 128.65, 129.21, 132.26, 134.47, 136.99, 166.58, 172.52 and 175.80; MS: m/z 294 [M]”1
