Efficient synthesis of 2-ethoxycarbonyl indoles

An efficient one-pot procedure for the synthesis of 2-ethoxycarbonyl indoles from commercially available materials has been developed. The one-step procedure involves in situ formation of the hydrazones from phenylhydrazine hydrochloride and ethyl pyruvate in the presence of bismuth nitrate followed by Fischer cyclization in polyphosphoric acid and ethanol. This method is efficient and simple.

An analytical perspective on favoured synthetic routes to the psychoactive tryptamines

Many tryptamine derivatives are known to induce altered states of consciousness and are increasingly of interest in forensic and neurobiological studies. The analytical chemistry of certain synthetic routes to the tryptamines is discussed and likely side products and impurities identified, where literature reports are available. Recent examples from the authors’ laboratory are presented to highlight future prospects and implications for analytical procedures. The aim of this review is to provide the analytical chemist with the foundation chemistry and some analytical targets to be able to undertake direct characterisation of products and intermediates. These might become available from interdiction of clandestine operations in a forensic environment or during the synthesis of the tryptamines for investigative neurobiological and clinical procedures.

Enantioselective Synthesis of Tertiary alpha,alpha-Diaryl Carbonyl Compounds Using Chiral N,N?-Dioxides under Umpolung Conditions

Br¡ãnsted acid-catalyzed addition of the chiral N,N?-dioxide into ynamides generated enolonium ions in situ which underwent enantioselective alkylation by indoles, pyrroles, and phenols, without racemization of the formed tertiary center. This external oxidant approach allows for the use of unmodified nucleophiles and does not leave trace groups from the oxidant, which significantly increases the synthetic efficiency and the product diversity. Furthermore, the byproduct of the N,N?-dioxide could be efficiently recycled into an optically pure form.

Expedient Synthesis of Substituted Benzoheterocycles using 2-Butoxy-2,3-dihydrofurans as [4+2] Benzannulation Reagents

2-Alkoxy-2,3-dihydrofurans were found to be versatile benzannulation reagents. Indoles can be synthesized in good to excellent yields via the [4+2] annulation of 2-butoxy-2,3-dihydrofuran with pyrroles catalyzed by copper bromide. With the same protocol, carbazoles can also be obtained when indoles are used as starting material with the aid of p-toluenesulfonic acid. This type of benzannulation reagent can also be used to synthesize benzofuran, benzothiophene and naphthalene derivatives in the presence of a catalytic amount of triflic acid in moderate yields. This benzannulation protocol features wide substrate scope and mild reaction condition. Moreover, most of examples have a good regioslectivity. (Figure presented.) .

The invention discloses a method for preparing 1-methyl cyclopropane carboxylic acid and belongs to the fields of fine chemical engineering and medical intermediates. The method comprises the following steps: by taking methacrylic acid (ester or salt), or methacrylonitrile or methacrylamide as a raw material, carrying out a cyclopropanation reaction with trihalide in the presence of an alkali to generate 2,2-geminal halide (III); carrying out a reaction between the 2,2-geminal halide (III) and metallic sodium to remove halogen atoms on the ring so as to generate methyl cyclopropionate or methyl cyclopropaneacetonitrile or methyl cyclopropylamide (II); acidifying the methyl cyclopropanecarboxylate, thereby obtaining 1-methyl cyclopropane carboxylic acid (I); and performing basic hydrolysis on methyl cyclopropaneacetonitrile or methyl cyclopropylamide, and acidifying to obtain 1-methyl cyclopropane carboxylic acid (I).

New approach in the characterization of bioactive compounds isolated from Calycotome spinosa (L.) Link leaves by the use of negative electrospray ionization LITMSn, LC-ESI-MS/MS, as well as NMR analysis

Two novel compounds were isolated for the first time from Calycotome spinosa (L.) Link, an alkaloid 5-Hydroxy-1H-indole (4) and a cyclitol D-pinitol (5), together with the three well-known flavonoids; Chrysin-7-O-(beta-D-glucopyranoside) (1), Chrysin-7-O-beta-D-(6?-acetyl)glycopyranoside (2) and Apigenin-7-O-beta-D-glycopyranoside (3). The chemical structures of the isolated compounds were elucidated by spectroscopic data and mass spectrometric analyses; including a fresh approach 1D-NMR, 2D-NMR with LC-ESI-MS/MS. In this study, the new compound (4) that has been obtained from the leaves MeOH extract presented the best radical scavenging activity (DPPH) (IC50 < 10 mug/mL) compared to the standard butylated hydroxytoluene (BHT, IC50 = 34.73 ¡À 0.23 mug/mL) and showed the highest total antioxidant capacity (TAC = 985.54 ¡À 0.13 mg AAE/g extract) in contrast to ascorbic acid (TAC = 905.95 ¡À 0.07 mg AAE/g extract). Furthermore, the strongest reducing power (EC50 = 344.82 ¡À 0.02 mug/mL), as well as the remarkable scavenging potential by ABTS assay (IC50 = 7.8 ¡À 0.43 mug/mL), were exhibited by the same composite (4). Followed by the methanol crude extract and the compound (3) that also showed a potent antioxidant (DPPH; IC50 = 41.04 ¡À 0.15 and 47.36 ¡À 0.21 mug/mL, TAC; 671.02 ¡À 0.21 and 608.67 ¡À 0.34 mg AAE/g extract, FRAP; EC50 = 763.73 ¡À 0.32 and 814.61 ¡À 0.31 mug/mL, ABTS; IC50 = 19.18 ¡À 0.06 and 63.72 ¡À 0.64 mug/mL, respectively), but less than the previous samples. On the opposite side, compound (5) had the lowest activity, in which its values were less interesting to determine. Moreover, compound (4) has equally exerted an attractive antibacterial activity against Staphylococcus aureus (ATTC-25923), Pseudomonas aeruginosa (ATTC- 27853) and Salmonella abony (NCTC 6017), as measured by the disc diffusion assay, with inhibition zones of 16 ¡À 0.5, 9.83 ¡À 0.29 and 8 ¡À 0.28 mm, in that order. To the best of our knowledge, 5-Hydroxy-1H-indole was isolated from plants for the second time in our current work. Thus, the obtained results from this investigation propose that the leaves of C. spinosa are a rich natural source for value molecules as potential antioxidants and antimicrobial agents for best human health.

Functional Genomics Insights Into the Pathogenicity, Habitat Fitness, and Mechanisms Modifying Plant Development of Rhodococcus sp. PBTS1 and PBTS2

Pistachio Bushy Top Syndrome (PBTS) is a recently emerged disease that has strongly impacted the pistachio industry in California, Arizona, and New Mexico. The disease is caused by two bacteria, designated PBTS1 that is related to Rhodococcus corynebacterioides and PBTS2 that belongs to the species R. fascians. Here, we assessed the pathogenic character of the causative agents and examined their chromosomal sequences to predict the presence of particular functions that might contribute to the observed co-occurrence and their effect on plant hosts. In diverse assays, we confirmed the pathogenicity of the strains on ?UCB-1? pistachio rootstock and showed that they can also impact the development of tobacco species, but concurrently inconsistencies in the ability to induce symptoms were revealed. We additionally evidence that fas genes are present only in a subpopulation of pure PBTS1 and PBTS2 cultures after growth on synthetic media, that these genes are easily lost upon cultivation in rich media, and that they are enriched for in an in planta environment. Analysis of the chromosomal sequences indicated that PBTS1 and PBTS2 might have complementary activities that would support niche partitioning. Growth experiments showed that the nutrient utilization pattern of both PBTS bacteria was not identical, thus avoiding co-inhabitant competition. PBTS2 appeared to have the potential to positively affect the habitat fitness of PBTS1 by improving its resistance against increased concentrations of copper and penicillins. Finally, mining the chromosomes of PBTS1 and PBTS2 suggested that the bacteria could produce cytokinins, auxins, and plant growth-stimulating volatiles and that PBTS2 might interfere with ethylene levels, in support of their impact on plant development. Subsequent experimentation supported these in silico predictions. Altogether, our data provide an explanation for the observed pathogenic behavior and unveil part of the strategies used by PBTS1 and PBTS2 to interact with plants.
