In 2013,Li, Meiling; Woods, Philip A.; Smith, Martin D. published 《Cation-directed enantioselective synthesis of quaternary-substituted indolenines》.Chemical Science published the findings.Formula: C8H6BrN The information in the text is summarized as follows:

An asym. method for the synthesis of quaternary-substituted indolenines via a 5-endo-dig cyclization of an α-cyanocarbanion onto an isonitrile was developed. This transformation relies on Broensted acid activation of the isonitrile functional group under asym. phase transfer conditions in the presence of a Broensted base. Good to excellent levels of enantioselectivity were obtained (85 : 15 to 96 : 4 e r., 18 examples) using a bespoke bifunctional catalyst. Enantioenriched indolenines produced in this process can be intercepted by nucleophilic species with high levels of diastereoselectivity to generate complex indoline frameworks. This process offers a general asym. approach to reactions involving the isonitrile functional group. In the experiment, the researchers used many compounds, for example, 2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5Formula: C8H6BrN)

According to other reports, 2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5) is used in the preparation of diarylpyrimidines (DAPYs) as HIV-1 non-nucleoside reverse transcriptase inhibitors.Formula: C8H6BrN

《Continuous flow Suzuki-Miyaura couplings in water under micellar conditions in a CSTR cascade catalyzed by Fe/ppm Pd nanoparticles》 was published in Green Chemistry in 2020. These research results belong to Wood, Alex B.; Nandiwale, Kakasaheb Y.; Mo, Yiming; Jin, Bo; Pomberger, Alexander; Schultz, Victor L.; Gallou, Fabrice; Jensen, Klavs F.; Lipshutz, Bruce H.. Synthetic Route of C7H4BrN The article mentions the following:

The first demonstration of aqueous surfactant-enabled Suzuki-Miyaura couplings run under flow conditions was described. In addition, use of an even more challenging heterogeneous nanoparticle catalyst, containing only 800 ppm of Pd (i.e., 0.08 mol%) in the form of Fe/ppm Pd nanoparticles, was sufficient using a continuous stirred-tank reactor (CSTR). In the part of experimental materials, we found many familiar compounds, such as 2-Bromobenzonitrile(cas: 2042-37-7Synthetic Route of C7H4BrN)

2-Bromobenzonitrile(cas: 2042-37-7) is a precursor to the quinazolinones, a class of drugs used to treat autoimmune diseases and coronary heart disease. This substrate molecule undergoes a palladium-catalyzed coupling reaction to form an aromatic ring.

Lin, Yamei; Bu, Qingxia; Xu, Jiaxian; Liu, Xiao; Zhang, Xueping; Lu, Guo-Ping; Zhou, Baojing published their research in Molecular Catalysis in 2021. The article was titled 《Hf-MOF catalyzed Meerwein-Ponndorf-Verley (MPV) reduction reaction: Insight into reaction mechanism》.HPLC of Formula: 614-16-4 The article contains the following contents:

Hf-MOF-808 exhibits excellent activity and specific selectivity on the hydrogenation of carbonyl compounds via a hydrogen transfer strategy. Its superior activity than other Hf-MOFs is attributed to its poor crystallinity, defects and large sp. surface area, thereby containing more Lewis acid-base sites which promote this reaction. D. functional theory (DFT) computations are performed to explore the catalytic mechanism. The results indicate that alc. and ketone fill the defects of Hf-MOF to form a six-membered ring transition state (TS) complex, in which Hf as the center of Lewis stearic acid coordinates with the oxygen of the substrate mol., thus effectively promoting hydrogen transfer process. Other reactive groups, such as -NO2, C = C, -CN, of inadequate hardness or large steric hindrance are difficult to coordinate with Hf, thus weakening their catalytic effect, which explains the specific selectivity Hf-MOF-808 for reducing the carbonyl group. The experimental part of the paper was very detailed, including the reaction process of 3-Oxo-3-phenylpropanenitrile(cas: 614-16-4HPLC of Formula: 614-16-4)

Kenari, Marziyeh E.; Putman, Joshua I.; Singh, Ravi P.; Fulton, Brandon B.; Phan, Huy; Haimour, Reem K.; Tse, Key; Berthod, Alain; Lovely, Carl J.; Armstrong, Daniel W. published their research in Molecules in 2021. The article was titled 《Enantiomeric separation of new chiral azole compounds》.HPLC of Formula: 1194-02-1 The article contains the following contents:

Twelve new azole compounds (rec/R/S)-I (Ar = Ph, Bn, Bz, allyl, 3,5-bis(trifluoromethyl)phenyl; R = 2,5-dioxo-1-phenylpyrrolidin-3-yl, 2-ethoxy-1-hydroxy-2-oxoethyl), (rec/R/S)-II (R1 = Ph, 4-chlorophenyl, 4-fluorophenyl, 4-methoxyphenyl) and (rec/R/S)-III were synthesized through an ene reaction involving methylidene heterocycles IV and V and N-phenylmaleimide, producing four oxazoles II (R = 2,5-dioxo-1-phenylpyrrolidin-3-yl), five thiazoles I (R = 2,5-dioxo-1-phenylpyrrolidin-3-yl), and one pyridine derivative, III and Et glyoxylate for an oxazole II (R = 2-ethoxy-1-hydroxy-2-oxoethyl) and a thiazole compd I (R = 2-ethoxy-1-hydroxy-2-oxoethyl). The twelve azoles I, II and III have a stereogenic center in their structure. Hence, a method to sep. the enantiomeric pairs, must be provided if any further study of chem. and pharmacol. importance of these compounds is to be accomplished. Six chiral stationary phases were assayed: four were based on macrocyclic glycopeptide selectors and two on linear carbohydrates, i.e., derivatized maltodextrin and amylose. The enantiomers of the entire set of new chiral azole compounds I, II and III were separated using three different mobile phase elution modes: normal phase, polar organic, and reversed phase. The most effective chiral stationary phase was the MaltoShell column, which was able to sep. ten of the twelve compounds I, II and III in one elution mode or another. Structural similarities in the newly synthesized oxazoles II provided some insights into possible chiral recognition mechanisms. The results came from multiple reactions, including the reaction of 4-Fluorobenzonitrile(cas: 1194-02-1HPLC of Formula: 1194-02-1)

Herein, a 1,3-difunctionalization of cyclopropylamines that serve as a π nucleophile in a two-electron (2e) SN2-like ring opening pathway is described.

This 2e ring opening manifold overcomes the constraint of previously reported 1e protocol as demonstrated by successful activation of monocyclic tertiary cyclopropylamines. In the experiment, the researchers used many compounds, for example, 4-(Cyclopropylamino)benzonitrile(cas: 1019607-55-6Application of 1019607-55-6)

4-(Cyclopropylamino)benzonitrile(cas: 1019607-55-6) belongs to anime. Many important products require amines as part of their syntheses. Methylamine is utilized in the production of the analgesic meperidine (trade name Demerol) and the photographic developer Metol (trademark), and dimethylamine is used in the synthesis of the antihistamine diphenhydramine (trade name Benadryl), the solvent dimethylformamide (DMF), and the rocket propellant 1,1-dimethylhydrazine.
