Pottie, Eline published the artcileSynthesis and Functional Characterization of 2-(2,5-Dimethoxyphenyl)-N-(2-fluorobenzyl)ethanamine (25H-NBF) Positional Isomers, Recommanded Product: 2,3-Dimethoxybenzaldehyde, the main research area is fluorobenzyl phenylethanamine preparation psychedelic activity; Psychedelic; bioassay; new psychoactive substances; serotonin receptor; structure−activity relationship; synthesis.

Synthes of positional isomers of 25H-NBF, with two methoxy groups placed on different positions of the Ph group of the phenethylamine moiety. These isomers were then functionally characterized in an in vitro bioassay monitoring the recruitment of β-arrestin 2 to the 5-HT2AR through luminescent readout via the NanoBiT technol. The obtained results provide insight into the optimal substitution pattern of the Ph group of the phenethylamine moiety of N-benzyl derived substances, a feature so far mostly explored in the phenethylamines underived at the N-position. In the employed bioassay, the most potent substances were 24H-NBF (EC50 value of 158 nM), 26H-NBF (397 nM), and 25H-NBF (448 nM), with 23H-NBF, 35H-NBF, and 34H-NBF yielding μM EC50 values. A similar ranking was obtained for the compounds’ efficacy: taking as a reference LSD (lysergic acid diethylamide), 24H-, 26H-, and 25H-NBF had an efficacy of 106-107%, followed by 23H-NBF (96.1%), 34H-NBF (75.2%), and 35H-NBF (58.9%). The stronger activity of 24H-, 25H-, and 26H-NBF emphasizes the important role of the methoxy group at position 2 of the phenethylamine moiety for the in vitro functionality of NBF substances.

Niu, Haichan published the artcileStructure Guided Design, Synthesis, and Biological Evaluation of Novel Benzosuberene Analogues as Inhibitors of Tubulin Polymerization, Application In Synthesis of 86-51-1, the main research area is benzosuberene analog tubulin polymerization inhibitor vascular disrupting agent.

A promising design paradigm for small-mol. inhibitors of tubulin polymerization that bind to the colchicine site draws structural inspiration from the natural products colchicine and combretastatin A-4 (CA4). Our previous studies with benzocycloalkenyl and heteroaromatic ring systems yielded promising inhibitors with dihydronaphthalene and benzosuberene analogs featuring phenolic (KGP03 and KGP18; I and II, R = OH) and aniline (KGP05 and KGP156; I and II, R = NH2) congeners emerging as lead agents. These mols. demonstrated dual mechanism of action, functioning as both potent vascular disrupting agents (VDAs) and as highly cytotoxic anticancer agents. A further series of analogs was designed to extend functional group diversity and investigate regioisomeric tolerance. Ten new mols. were effective inhibitors of tubulin polymerization (IC50 < 5 μM) with seven of these exhibiting highly potent activity comparable to CA4, KGP18, and KGP03. For one of the most effective agents, dose-dependent vascular shutdown was demonstrated using dynamic bioluminescence imaging in a human prostate tumor xenograft growing in a rat.

Sen, Anirban published the artcileMechanistically Guided One Pot Synthesis of Phosphine-Phosphite and Its Implication in Asymmetric Hydrogenation, SDS of cas: 86-51-1, the main research area is mechanistically guided one pot phosphine phosphite preparation catalyst hydrogenation; alkene asym hydrogenation Senphos rhodium catalyzed.

Although hybrid bidentate ligands are known to yield highly enantioselective products in asym. hydrogenation (AH), synthesis of these ligands is an arduous process. Herein, a one pot, atom-economic synthesis of a hybrid phosphine-phosphite (L1) is reported. After understanding the reactivity difference between an O-nucleophile vs. C-nucleophile, one pot synthesis of Senphos (L1) was achieved (72%). When L1 was treated with [Rh], 31P NMR revealed bidentate coordination to Rh. Senphos, in the presence of rhodium, catalyzes the AH of Methyl-2-acetamido-3-phenylacrylate and discloses an unprecedented turn over frequency of 2289, along with excellent enantio-selectivity (92%). The generality is demonstrated by hydrogenating an array of alkenes. The AH operates under mild conditions of 1-2 bar H2 pressure, at room temperature The practical relevance of L1 is demonstrated by scaling-up the reaction to 1 g and by synthesizing DOPA, a drug widely employed for the treatment of Parkinson’s disease. Computational insights indicate that the R isomer is preferred by 3.8 kcal/mol over the S isomer.

Pramanik, Subhendu published the artcilePalladium-Catalyzed Benzannulations of 1-(Indol-2-yl)but-3-yn-1-ols: Easy Access to Functionalized Carbazoles, Computed Properties of 86-51-1, the main research area is carbazole preparation one pot; indolyl butynol aldehyde benzannulation cascade palladium catalyst.

An atom economic direct synthesis of carbazoles having aryl and keto-aryl groups has been achieved through Pd(II)-catalyzed cascade reactions between 1-(indol-2-yl)-3-butyn-1-ols and aldehydes. The reaction proceeds through alkyne-carbonyl metathesis, an uncommon pathway using palladium catalyst, and constitutes a fast intermol. assembly through four carbon-carbon bond formations in one-pot. Absence of the aldehyde substrate resulted in the formation of C1-aryl substituted carbazoles. The reaction is amenable to the synthesis of bis-carbazole derivatives

Gomez-Prado, Raul A. published the artcileSynthesis of nuevamine and a cyano-chilenine analog via divergent C(sp3)-H bond functionalization of isoindolinone derivatives, Synthetic Route of 86-51-1, the main research area is nuevamine cyanochilenine preparation.

Divergent C(sp3)-H bond functionalizations of isoindolinone derivatives were developed to synthesize nuevamine, a cyano-chilenine derivative, and two related analogs. A copper-catalyzed C-H cross-dehydrogenative coupling (via cation formation) allowed the formation of a new C-C bond leading to the direct assembly of the isoindolo[1,2-a]isoquinolinone tetracyclic system of the nuevamine. The syntheses of the cyano-chilenine derivatives were carried out by installing two nitrile groups under basic conditions (via anion formation). Then, the isoindolobenzazepinic system of the chilenine skeleton was constructed by a Houben-Hoesch cyclization process. The present methodol. has the advantage of not requiring the use of pre-functionalized substrates.

Aravindan, Narasingan published the artcileA Short Total Synthesis of Benzophenanthridine Alkaloids via a Rhodium(III)-Catalyzed C-H Ring-Opening Reaction, Quality Control of 86-51-1, the main research area is rhodium catalyst diastereoselective regioselective ring opening oxidation; benzophenanthridine alkaloid total synthesis.

The biol. important naturally available benzophenanthridines were prepared efficiently in three steps with overall good yields. A new synthetic methodol. involving a rhodium(III) catalyzed redox-neutral ring-opening of 7-azabenzonorbornadienes with aromatic aldoximes is developed to synthesize the target mols. The developed C-H ring-opening reaction is highly diastereoselective and compatible with various sensitive functional group substituted aromatic aldoximes as well as substituted 7-azabenzonorbornadienes. The ring-opening products were transformed into highly sensitive 13,14-dehydrobenzo phenanthridine derivatives by HCl hydrolysis. Subsequently, 13,14-dehydrobenzophenanthridines were converted into biol. important benzophenanthridine alkaloids in the presence of DDQ. A possible reaction mechanism was proposed for the C-H ring-opening reaction and supported by the deuterium labeling studies.
