Alkylideneindolenines are widely employed key electrophilic intermediates for the -functionalization of the C-3 side chain of indoles. However, the reactivity of their extended (vinylogous) counterparts has not been carefully explored so far. These intermediates can undergo 1,4- or 1,6-addition with functionalization at – or -position of the side chain, resulting in regioisomeric mixtures of products. This work demonstrates that a complete -regioselectivity can be achieved in the reaction of 3-indol-3-yl allylic alcohols with various nucleophiles. This process is catalysed by just 1mol% zinc(II) triflate at room temperature and entails the 1,6-selective addition of the nucleophile to an extended protonated alkylideneindolenine generated insitu. Indoles, pyrroles, anilines and thiols can be efficiently used as nucleophilic partners for this reaction, delivering the corresponding 3-vinyl substituted, -functionalised indole products in moderate to good yields.

A sensitive method has been established by using activated carbon as an adsorbent for extraction of indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) from bean sprout, tomato, potato, cucumber, and wheat grain prior to field-amplified sample injection-micellar electrokinetic capillary chromatography (FASI-MEKC) detection. Parameters affecting FASI and solid-phase extraction (SPE) were optimized in detail. Under the optimal conditions, the sensitivity of SPE-FASI-MEKC for IAA and IBA was respectively improved by 32.5 and 29.7 times as compared with the direct MEKC. The detection limits were 4.1 for IAA and 5.3 ng mL(-1) for IBA with 4.9-5.2% RSD (n = 9, C = 0.03 mu g mL(-1)). The new method has been successfully applied to detect IAA and IBA in bean sprout, tomato, potato, cucumber, and wheat grain with the recoveries of 81.7-110%.

The reaction of pentachloropyridine with indoles and bis(indolyl)methanes (BIMs) were investigated. Indoles in basic medium exclusively react with pentachloropyridine to give the correspondingN-perhalopyridine substituted indoles. Furthermore, BIMs in reaction with pentachloropyridine gaveN-perfluoropyridinated BIMs andN,N ‘-bis(perfluoropyridyl) bis(indolyl)methane derivatives, as major and minor products, respectively. The structures of all the compounds were confirmed by elemental analysis, IR,H-1 NMR and(13)C NMR spectroscopy.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

In current scenario, heterocyclic compounds’ role in medicinal chemistry has been tremendously increased as they possess wide number of pharmacological activities. One of the common heterocycles include indole skeleton with well-established biological significance in field of medicinal chemistry. Fusion of indole nucleus with pyrrole heterocycle constitutes pyrroloindole scaffold, which further modifies the existing properties of indole alone. Pyrroloindole is a privileged scaffold found in various types of bioactive entities including natural compounds and exhibits wide variety of pharmacological activities like muscle relaxant, antifungal, antitumor, and antibiotic. Therefore, it is considered as attractive template for drug discovery. From several years, numbers of synthetic strategies have been reported for the synthesis of pyrroloindole and its derivatives, including also natural compounds such as amauromine, yuremamine, and chimonanthines. Here, in this review, we have tried to compile various synthetic strategies of pyrroloindole and its derivatives.

In an article, author is Song Chunlan, once mentioned the application of 69-79-4, Name: Maltose, Name is Maltose, molecular formula is C12H22O11, molecular weight is 342.2965, MDL number is MFCD00135877, category is indole-building-block. Now introduce a scientific discovery about this category.

Dearomative annulation of indoles has emerged as a powerful tool for the preparation of polycyclic indoline-based alkaloids. Compared with well-established methods towards five-membered-ring-fused indolines, the six-membered-ring-fused indolines are rarely accessed under thermal conditions. Herein, a dearomative [4+2] annulation between different indoles is developed through an electrochemical pathway. This transformation offers a remarkably regio- and stereoselective route to highly functionalized pyrimido[5,4-b]indoles under oxidant- and metal-free conditions. Notably, this electrochemical approach maintains excellent functional-group tolerance and can be extended as a modification tactic for pharmaceutical research. Preliminary mechanism studies indicate that the electrooxidation annulation proceeds through radical-radical cross-coupling between an indole radical cation and an N-centered radical generated in situ.

A three-component reaction of indoles, alpha-bromoacetaldehyde acetals, and ketones was developed by using bismuth(III) triflate as the catalyst to realize a straightforward approach for synthesizing carbazole derivatives. The reaction was established mechanistically through the autotandem catalysis of Bi(OTf)(3) in the following two steps: (i) Friedel-Crafts-type alkylation of indole with alpha-bromoacetaldehyde acetal, which produced a tryptaldehyde-type intermediate and (ii) [4 + 2] annulation of this intermediate with the ketone component.

Salmonellosis in poultry is an important disease that seriously impedes the development of the poultry industry. The increased resistance to antimicrobials against Salmonella has been a major public health concern worldwide. We conducted a study from January to June 2016 in and around the Rajshahi district of Bangladesh on the commercial chicken to isolate, identify and characterize poultry-specific Salmonella, to assess the potential risk factors and to determine the antimicrobial resistance pattern of the isolates. The overall prevalence of Salmonella enterica was 41% (49/120) [95% CI: 31.95%-50.17%] with 41.7% in broiler chicken (25/60) [95% CI: 29.06%-55.12%] and 40% in layer chicken (24/60, 40%) [95% CI: 27.56%-53.46%]. Samples collected from Rajshahi city (OR = 1.37, 95% CI: 0.50-3.73) and Puthia Upazila (OR = 1.51, 95% CI: 0.56-4.12) were more likely to be positive for Salmonella than Charghat Upazila. Salmonella detection was 1.3 times higher in chicken, providing loose feed than those provided ready feed. All the isolates fermented dextrose, maltose and mannitol with the production of acid and gas, but did not ferment sucrose and lactose. The isolates showed catalase, MR, citrate utilization test and TSI agar test positive, but indole and V-P tests negative. Salmonella isolates were sensitive to ciprofloxacin (90%), gentamycin (80%), amoxicillin (75%), streptomycin (70%), ampicillin (45%) and sulfamethoxazole-trimethoprim (45%), whereas highly resistant to penicillin (100%) and nalidixic acid (100%) followed by sulfamethoxazole-trimethoprim (55%), ampicillin (40%) and amoxicillin (25%). Salmonella enterica is endemic in commercial chicken production in Bangladesh with high prevalence. A considerable proportion of Salmonella isolates was found to be resistant to the majority of the common antimicrobial drugs. A good biosecurity system could be effective for the reduction of Salmonella. It is necessary to obtain universal commitments to establish prudent antibiotic use policies.
