Dispersion-Controlled Regioselective Acid-Catalyzed Intramolecular Hydroindolation of cis-Methindolylstyrenes To Access Tetrahydrobenzo[cd]indoles

Readily prepared cis-beta-(alpha’,alpha’-dimethyl)-4′-methindolylstyrenes undergo acid-catalyzed intramolecular hydroindolation to afford tetrahydrobenzo[cd]indoles. Our experimental and computational investigations suggest that dispersive interactions between the indole and styrene preorganize substrates such that 6-membered ring formation is preferred, apparently via concerted protonation and C-C bond formation. When dispersion is attenuated (by a substituent or heteroatom), regioselectivity erodes and competing oligomerization predominates for cis substrates. Similarly, all trans-configured substrates that we evaluated failed to cyclize efficiently.

An insight into the medicinal perspective of synthetic analogs of indole: A review

Heterocycles occupy a salient place in chemistry due to their wide range of activity in the fields of drug design, photochemistry, agrochemicals, dyes, and so on. Amongst all, indole scaffold is considered as one of the most promising heterocycles found in natural and synthetic sources and has been shown to possess various biological activity, including anti-inflammatory, anti-HIV, antitubercular, antimalarial, anticonvulsant, antidiabetic, antihypertensive, analgesics, antidepressant, anticancer, antioxidant, antifungal, and antimicrobial, etc. All the reported indole molecules bind to multiple receptors with high affinity, thus expedite the research on the development of novel biologically active compounds through the various approach. In this review, we aimed to highlight synthetic and medicinal perspective on the development of indole-based analogs. In addition, structural activity relationship (SAR) study to correlate for their biological activity also discussed. (C) 2019 Elsevier Masson SAS. All rights reserved.

Enantioselective Synthesis of 2-Amino-1,1-diarylalkanes Bearing a Carbocyclic Ring Substituted Indole through Asymmetric Catalytic Reaction of Hydroxyindoles with Nitroalkenes

An asymmetric catalytic reaction of hydroxyindoles with nitroalkenes leading to the Friedel-Crafts alkylation in the carbocyclic ring of indole is presented. The method is based on the activating/directing effects of the hydroxy group situated in the carbocyclic ring of the indole providing nitroalkylated indoles functionalizated at the C-4, C-5, and C-7 positions with high yield, regio-, and enantioselectivity. The optically enriched nitroalkanes were transformed efficiently in optically enriched 2-amino-1,1-diarylalkanes bearing a carbocyclic ring substituted indole.

Development of a fragmentation pattern of synthetic cannabinoids based on electrospray ionization mass spectrometry in positive ion mode to screen synthetic cannabinoids in illicit products

To explore the MS fragmentation pattern of synthetic cannabinoids by electrospray ionization mass spectrometry, twenty-seven synthetic cannabinoids were systematically investigated by liquid chromatography coupled to high-resolution quadrupole Orbitrap mass spectrometry(LC-Q-Orbitrap/MS)with positive mode of electrospray ionization. Based on tandem multistage MS and high resolution MS data, MS fragmentation pattern of synthetic cannabinoids was summarized. The cleavage of C-C bonds next to the oxygen at the side chain on the C-3 position of synthetic cannabinoids was the characteristic fragmentation pathway of synthetic cannabinoids in the positive mode of electrospray ionization. When the synthetic cannabinoids with a 3-carbamoylpropyl-indole/indazole structure, NH3, CO, NH2CHO and CH2(CH3)(2) were easy to lose to form different ions. While when the synthetic cannabinoids with a 3-carboxamide-indole/indazole structure, the side chain on the C-3 position was susceptible to gamma-cleavage. In addition, this MS fragmentation pattern was applied to quickly screen whether electronic cigarette oil and tobacco from drug cases contain synthetic cannabinoids. This kind of compounds had strong fragmentation pattern, which provided new evidence for the rapid structure identification of synthetic cannabinoids. (C) 2020 Elsevier B.V. All rights reserved.

Synthesis of imidazopyridine-fused indoles via one-pot sequential Knoevenagel condensation and cross dehydrogenative coupling

A simple and efficient strategy for the synthesis of imidazopyridine-fused indoles has been developed that involves one-pot sequential Knoevenagel condensation of readily available active methylene azoles with N-substituted-1H-indole-3-carboxaldehydes or N-substituted-1H-indole-2-carboxaldehydes followed by palladium-catalyzed intramolecular cross dehydrogenative coupling reaction. A series of 36 derivatives was prepared by using this strategy. The products were obtained in moderate to excellent (32-94%) yields and showed broad substrate scope with tolerance of various functional groups and was amiable for gram scale preparation without problems.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 171228-49-2. COA of Formula: C37H42F2N8O4.
