On June 30, 2007, Abd El-Latif, Nehad A.; Amr, Abd El-Galil E.; Ibrahiem, Alhusain A. published an article.Formula: C12H7N3 The title of the article was Synthesis, reactions, and pharmacological screening of heterocyclic derivatives using nicotinic acid as a natural synthon. And the article contained the following:

A series of substituted pyridine derivatives were prepared from 3-acetylpyridine, which was prepared from the corresponding nicotinic acid as a natural starting material. Reaction of 3-acetylpyridine with indole-3-carboxaldehyde afforded the corresponding 3-β-(3-indolyl)(acryloyl)pyridine, which was treated with hydroxylamine hydrochloride in pyridine or acetic acid in the presence of sodium acetate to afford 3-β-(3-indolyl)(acryloyl)pyridine oxime and oxazole derivatives The oxime was treated with Et isothiocyanate or toluene-3,5-diisocyanate in refluxing dioxane to give the corresponding Et thiosemicarbazide and 3,5-bis(semicarbazide) derivative 3-β-(3-Indolyl)(acryloyl)pyridine was condensed with malononitrile in refluxing ethanol in the presence of piperidine as a catalyst to give a cyano(amino)pyran derivative, while it was condensed with Et cyanoacetate or malononitrile in the presence of ammonium acetate to yield (cyano)pyridone and cyano(amino)pyridine derivatives Cyclization of (acryloyl)pyridine with o-phenylenediamine in refluxing butanol led to the formation of the corresponding benzodiazepine via the intermediate A. Finally, cycloaddition reaction of (acryloyl)pyridine with thiourea yielded thioxopyrimidine, which was treated with chloroacetic acid to yield thiazolopyrimidine. An arylmethylene derivative was prepared by reacting thiazolopyrimidine with indole-3-carboxaldehyde or by treating thioxopyrimidine with indole-3-carboxaldehyde and chloroacetic acid in one step. The pharmacol. screening showed that many of the compounds thus prepared have good analgesic and anticonvulsant activities comparable to valdecoxib [i.e, 4-(5-methyl-3-phenyl-4-isoxazolyl)benzenesulfonamide] and carbamazepine as reference drugs. The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).Formula: C12H7N3

Belley, Michel; Sauer, Effiette; Beaudoin, Daniel; Duspara, Petar; Trimble, Laird A.; Dube, Pascal published an article in 2006, the title of the article was Synthesis and reactivity of N-hydroxy-2-aminoindoles.Reference of 2-(2-Nitro-4-(trifluoromethyl)phenyl)acetonitrile And the article contains the following content:

Catalytic hydrogenation of (2-nitrophenyl)acetonitriles I (R1 = H, Cl, F, F3C, MeO, MeSO2, MeCONH; R2 = EtO2C, CN, MeSO2, PhSO2) bearing an electron-withdrawing substituent α to the nitrile, using Pd/C and (Ph3P)4Pd, affords N-hydroxy-2-aminoindoles II in good to excellent yields.

On August 6, 2021, Liu, Lu; Li, Lei; Wang, Xin; Sun, Ran; Zhou, Ming-Dong; Wang, He published an article.Reference of 2-(2-Nitro-4-(trifluoromethyl)phenyl)acetonitrile The title of the article was Mn(III)-Mediated Radical Cyclization of o-Alkenyl Aromatic Isocyanides with Boronic Acids: Access to N-Unprotected 2-Aryl-3-cyanoindoles. And the article contained the following:

The synthesis of N-unprotected 2-aryl-3-cyanoindoles was realized via the Mn(III)-mediated radical cascade cyclization of o-alkenyl aromatic isocyanides with boronic acids. A possible mechanism involving a sequential intermol. radical addition, intramol. cyclization, and cleavage of the C-C bond under mild reaction conditions is proposed. Mechanism studies show that H2O or O2 might provide the oxygen source for the elimination of benzaldehyde.
