Phatake, Vishal V. published the artcile[TBDH][HFIP] ionic liquid catalyzed synthesis of quinazoline-2,4(1H,3H)-diones in the presence of ambient temperature and pressure, Computed Properties of 1885-29-6, the main research area is quinazolinedione preparation green chem bifunctional protic ionic liquid catalyst; aminobenzonitrile carbon dioxide cyclization.

The utilization of carbon dioxide under mild reaction conditions is an important aspect of the sustainable chem. point of view. Herein, authors prepared three bifunctional protic ionic liquids having 1,5,7-Triazabicyclo[4.4.0]dec-5-ene (TBD) as a cation and an alc. anions were prepared by simple neutralization of the super base TBD with proton donor alcs. such as hexafluoroisopropanol (HFIP), TFE (2,2,2-Trifluoroethanol) and TFA (2,2,2-Trifluoroacetic acid). These PILs were used as catalysts for chem. fixation of carbon dioxide into quinazoline-2,4(1H,3H)-diones. [TBDH+][HFIP-] protic ionic liquid (PIL) shows very good result compare to other PILs. As a bifunctional ionic liquid, it simultaneously activates 2-aminobenzonitrile as well as CO2 and shows excellent performance for the conversion of 2-aminobenzonitrile to quinazoline-2,4(1H,3H)-diones in presence of CO2 balloon pressure at 35°C temperature Moreover, the [TBDH+][HFIP-] PIL can be recycled up to six recycle run.

Penaranda Gomez, Angelica published the artcileI2/DMSO-Promoted Synthesis of Chromeno[4,3- b]quinolines through an Imine Formation/Aza-Diels-Alder/Aromatization Tandem Reaction under Metal-Catalyst- and Photosensitizer-Free Conditions, SDS of cas: 1885-29-6, the main research area is cinnamyl salicylaldehyde aryl amine iodine catalyst tandem reaction; chromenoquinoline preparation green chem.

A tandem approach was developed for the efficient synthesis of substituted chromeno[4,3- b]quinolines from arylamines and O-cinnamyl salicylaldehydes under metal-catalyst- and photosensitizer-free reaction conditions. This method was based on an inexpensive I2/DMSO system in which mol. iodine first acted as a Lewis acid to promote the formation of the corresponding imine bearing the alkene moiety; then, this species fulfilled a second role by catalyzing an intramol. aza-Diels-Alder cycloaddition to generate the resp. tetrahydrochromenoquinoline as an intermediate. Finally, the dual behavior of DMSO as an oxidant and as a solvent proved crucial at this stage, allowing the regeneration of I2 and promoting the aromatization of the tetrahydrochromenoquinoline intermediates to yield the desired 7-aryl-6 H-chromeno[4,3- b]quinolines. This protocol was mild and easy to perform, features high step-economy (tandem process) and provides a new access to biol. important nitrogen- and oxygen-containing heterocyclic mols.

Wilders, Alison M. published the artcilePd-Catalyzed Cross-Coupling of Hindered, Electron-Deficient Anilines with Bulky (Hetero)aryl Halides Using Biaryl Phosphorinane Ligands, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is Buchwald Hartwig amination aryl halide palladium phosphine phosphorinane catalyst; phosphorinane oxo preparation phospha Michael addition cyclization dienone; primary phosphine phospha Michael reaction preparation oxophosphorinane amination catalyst; high throughput evaluation Buchwald Hartwig amination aryl halide aniline.

Biaryl phosphorinane ligands derived from addition of biaryl primary phosphines to trans,trans-dibenzylideneacetone (AlisonPhos and AliPhos) form highly active ligands for Pd-catalyzed coupling of hindered, electron-deficient anilines with hindered (hetero)aryl halides, a challenging class of C-N cross-coupling reaction with few precedents. Broad substrate scope and functional group tolerance were observed under the reaction conditions. Computational studies suggest that ligands containing Ph substituents provide greater activity through more favorable aniline binding in the catalytic cycle in comparison to alkyl-substituted phosphorinanes. A general and high-yielding procedure for the synthesis of biaryl phosphorinanes by phospha-Michael addition of primary biarylphosphines to 1,4-dien-3-ones in 1,1,1,3,3,3-hexafluoroisopropanol (HFIP), under relatively mild conditions (23-110°C), is also described. HFIP as the solvent significantly accelerates the phospha-Michael addition, allowing the preparation of previously inaccessible ligands and higher yields overall.

Saritha, Rajendhiran published the artcileCarbazole based Electron Donor Acceptor (EDA) catalysis for the synthesis of biaryl and aryl-heteroaryl compounds, HPLC of Formula: 1885-29-6, the main research area is phenyldiazonium tetrafluoroborate arene tetrahydrocarbazole catalyst Gomberg Bachmann arylation; biaryl preparation.

A highly regioselective, carbazole based Electron Donor Acceptor (EDA) catalyzed synthesis of biaryl and aryl-heteroaryl compounds was described. Various indole and carbazole derivatives were screened for the Homolytic Aromatic Substitution (HAS) reaction. Tetrahydrocarbazole (THC) was very efficient for the HAS transformation and proceeded via a complex formation between diazonium salt and electron rich tetrahydrocarbazole. The UV-Vis spectroscopy technique was used to confirm the complex formation. The in-situ generated EDA complex even in a catalytic amount was found to be efficient for the Single Electron Transfer (SET) process without any photoactivation. Biaryl compounds, 2-phenylfuran, 2-phenylthiophene and 2-phenylpyrrole and bioactive compounds such as dantrolene and canagliflozin were synthesized in moderate to excellent yields.

Saritha, Rajendhiran published the artcileMetal-free, regioselective, visible light activation of 4CzIPN for the arylation of 2H-indazole derivatives, Name: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is arylated indazole regioselective preparation; indazole aniline arylation tetrakiscarbazolyl dicyanobenzene photocatalyst.

Highly regioselective organo photocatalysis of 4CzIPN (1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene) for the arylation of 2H-indazole was demonstrated to obtain arylated indazole derivatives I [R1 = H, Cl, Br, CN; R2 = H, Cl; R3 = H, F, MeO, etc.; R4 = Ph, 4-FC6h4, Bn, etc.; R5 = H, MeO]. The present synthetic route provided a highly safe and easily accessible aniline precursor as an arylation reagent. The photoactivated 4CzIPN organocatalyst was found to be more efficient for single electron transfer without any organic base for the radical reaction. The carbazole-based photocatalyst (4CzIPN) with wide redox potential was stable and recyclable for further reaction transformations. Many indazole and aniline derivatives were used in the reaction and provided the arylated indazole derivatives in good to excellent yield.

Rodriguez-Villar, Karen published the artcileSynthesis, antiprotozoal activity, and cheminformatic analysis of 2-Phenyl-2H-indazole derivatives, COA of Formula: C7H6N2, the main research area is phenylindazole preparation cheminformatic antiprotozoal activity SAR; Entamoeba histolytica; Giardia intestinalis; Trichomonas vaginalis; indazole; structure-activity relationships.

Herein, a series of indazole derivatives I [R = H, Cl, OMe, CF3, etc.; R1 = H, Cl, OMe, C(O)OCH3, etc.; R2 = H, C(O)OH, F, OH, etc.] was synthesized and studied as antiprotozoals. The 2-phenyl-2H-indazole scaffolds I were accessed by a one-pot procedure, which includes a combination of ultrasound synthesis under neat conditions as well as Cadogan’s cyclization. Moreover, some compounds were derivatized to have an appropriate set to provide structure-activity relationships (SAR) information. Whereas the antiprotozoal activity of six of these compounds against E. histolytica, G. intestinalis, and T. vaginalis had been previously reported, and the activity of the addnl. 16 compounds I was evaluated against these same protozoa. The biol. assays revealed structural features that favor the antiprotozoal activity against the three protozoans tested, e.g., electron withdrawing groups at the 2-Ph ring. It is important to mention that the indazole derivatives I possess strong antiprotozoal activity and are also characterized by a continuous SAR.

A solvent- and metal-free protocol for preparation of N-aryl substituted azacycles I (R1 = Ph, 2,4-difluorophenyl, 3-methylphenyl, etc.; R2 = H, Me; n = 1, 2; R3R4 = H, CH2=CH-CH=CH2) from arylamines R1NH2 and cyclic ethers such as THF, 2-methyloxolane, oxane, etc. is described. In this method, the combination of POCl3 and DBU is crucial for conversion of arylamines and cyclic ethers to five- and six-membered azacycles I. Without solvent, a variety of N-aryl-substituted, five-membered azacycles (pyrrolidines, 2-methylpyrrolidines, and piperidine) and six-membered azacycles (isoindolines and tetrahydroisoquinolines) I is synthesized in high yields. This green method provides a sustainable and efficient approach for the preparation of azacycles I from various cyclic ethers.
