Background: The vernacular name ‘Harmal’ is used for two plant species in Saudi Arabia, i.e. Peganum harmala L. and Rhazya stricta Decne. Both are important medicinal plants which offer interesting pharmacological properties. Objective: This study aimed to evaluate the genetic diversity among different populations of harmal based on chemical variations of alkaloids and molecular polymorphism. Methods: Total alkaloids were extracted from plants of three populations of each species and estimated by using spectrophotometer and the chemical compounds were analyzed by Gas chromatography mass spectrometry (GC-MS). Molecular polymorphism was estimated by using the Inter Simple Sequence Repeat (ISSR) fingerprints. Results: The results showed that the alkaloids content of R. stricta was higher than P. harmala populations. The GC-MS analysis revealed the presence of (65-53) compounds in R. stricta and P. harmala, and the percentage of polymorphism was found to be 93.2%. Sixteen ISSR primers produced 170 scorable bands with an average of 9.6 bands per primer and 75%-100% polymorphism. The cluster analysis using the unweighted pair-group method of the arithmetic average (UPGMA) method based on combined data of GC-MS and ISSR markers divided the six harmal genotypes into two major groups. Conclusion: The existence of variations in chemical and genetic markers is useful for the selection of potential genotypes for medicinal use, and for breeding lines for medicinal substances production to spare wild plants from uncontrolled harvesting for folk medicine.

Various aromatic bromides and iodides were smoothly converted into the corresponding aromatic nitriles in good to moderate yields by the treatment with n-butyllithium and subsequently DMF, followed by treatment with molecular iodine in aq NH3. The same treatment of typical aromatics and heteroaromatics with n-butyllithium and subsequently DMF, followed by treatment with molecular iodine in aq NH3 also provided the corresponding aromatic nitriles in good yields. Moreover, the same treatment of aromatic bromides and aromatics with half amount of DIH (1,3-diiodo-5,5- dimethylhydantoin) instead of molecular iodine worked effectively to give the corresponding aromatic nitriles, respectively, in good yields. These reactions are novel and environmentally benign one-pot methods for the preparation of aromatic nitriles from aromatic bromides and aromatics, respectively, through the formation of aryllithiums and their DMF adducts.

The presence of salicylic acid (10 mol-%) and H2O (10 equiv.) significantly improves the arylation-lactonization sequence of gamma-alkenoic acids with in situ formed diazonium salts (from bench stable anilines). The reaction is finished in less than 5 h without thermal or photochemical activation, giving access to a variety of gamma,gamma-disubstituted butyrolactones. The protocol is user-friendly and can be used at gram-scale or adapted to transform alkenols into phthalanes. Control experiments revealed that aryl radicals participate in the reaction and a plausible mechanism is proposed to include this and other mechanistic investigations, for the catalyzed and the background reaction.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 652-39-1, and how the biochemistry of the body works.COA of Formula: C8H3FO3

54109-03-4, Name is 5-Chloroisobenzofuran-1(3H)-one, belongs to benzofurans compound, is a common compound. COA of Formula: C8H5ClO2In an article, once mentioned the new application about 54109-03-4.

The direct carbonylation of C-H bonds in the benzene ring of N-phenylpyrazoles via catalysis by ruthenium or rhodium complexes is described. The reaction of N-phenylpyrazoles with carbon monoxide and ethylene in the presence of Ru3(CO)12 or Rh4(CO)12 resulted in the site-selective carbonylation of the ortho C-H bonds in the benzene ring to give the corresponding ethyl ketones. A variety of functional groups on the benzene ring can be tolerated. N-Phenylpyrazoles have higher reactivities than would be expected, based on the pKa values of the conjugate acid of pyrazole. The choice of solvent for this reaction is significant, and N, N-dimethylacetamide (DMA) gives the best result.

Electric Literature of 4265-16-1, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 4265-16-1, Name is Benzo[b]furan-2-carboxaldehyde, molecular formula is C9H6O2.

Auto-tandem catalysis (ATC), in which a single catalyst promotes two or more mechanistically different reactions in a cascade pattern, provides a powerful strategy to prepare complex products from simple starting materials. Reported here is an unprecedented auto-tandem cooperative catalysis (ATCC) for Morita?Baylis?Hillman carbonates from isatins and allylic carbonates using a simple Pd(PPh3)4 precursor. Dissociated phosphine generates phosphorus ylides and the Pd leads to pi-allylpalladium complexes, and they undergo a gamma-regioselective allylic?allylic alkylation reaction. Importantly, a cascade intramolecular Heck-type coupling proceeds to finally furnish spirooxindoles incorporating a 4-methylene-2-cyclopentene motif. Experimental results indicate that both Pd and phosphine play crucial roles in the catalytic Heck reaction. In addition, the asymmetric versions with either a chiral phosphine or chiral auxiliary are explored, and moderate results are obtained.

Application of 18959-30-3, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 18959-30-3, 4,5-Difluorophthalic Anhydride, introducing its new discovery.

To provide high-temperature polyimide matrix resins, novel carborane-containing thermosetting polyimides are presented. First, the low-viscosity carborane-containing imide oligomers are synthesized using newly designed 1-(3-amino-4-tolyl)-2-(4-aminophenyl)-o-carborane and aromatic dianhydride as monomers, 4-phenylethynyl phthalic anhydride as the end-capping reagent. Followed by thermal curing, the resulting polyimides show high Tg (?500 C) and above 92.1% char yield at 800 C both in nitrogen and air atmosphere due to the incorporation of the bulky carborane cages. Aging studies, performed at 400 and 500 C for 5 h in air on a carborane-containing polyimide and a carborane-free polyimide, show that the polyimide with carborane groups possesses excellent thermo-oxidative stability. Moreover, the novel polyimides exhibit constant and relatively low coefficient of thermal expansion values over a wide range of temperature, indicative of a remarkable dimensional stability. Thus, this study clearly demonstrates the viability of the incorporation of carborane cages to access polyimide thermosets with ultrahigh Tg and thermo-oxidative stability.
