TBAB-Catalyzed Csp3?N Bond Formation by Coupling Pyridotriazoles with Anilines: A New Route to (2-Pyridyl)alkylamines

A new metal-free procedure allowing Csp3?N bond formation through coupling of pyridotriazoles and weakly nucleophilic anilines has been developed. This sustainable reaction shows high tolerance towards functional groups (ketones, free alcohols) leading to 2-picolylamine derivatives. The key to our success is the use of a catalytic amount of TBAB and water as a co-solvent leading to the formation of pyridylalkylamine derivatives. As this coupling tolerates the presence of Csp2?Br bond on both partners of the reaction, we performed a sequential one-pot reaction between functionalized triazolopyridines and anilines followed by a second coupling with N-tosylhydrazones leading to the formation of Csp3?N and Csp2?Csp2 bonds.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: benzodioxans, you can also check out more blogs about22013-33-8

Selective C(sp3)?H and C(sp2)?H Fluorination of Alcohols Using Practical Auxiliaries

Selective introduction of fluorine into molecules by the cleavage of inert C?H bonds is of central academic and synthetic interest, yet remains challenging. Given the central role of alcohols in organic chemistry as the most ubiquitous building blocks, a versatile and selective C(sp3)?H and C(sp2)?H fluorination of simple alcohols, enabled by novel designed exo-directing groups, is described. C(sp2)?H bond fluorination was achieved by using a simple acetone oxime as auxiliary, whereas a new, modular and easily accessible bidentate auxiliary was developed for the efficient and site-selective fluorination of various primary methyl, methylene, and benzylic C(sp3)?H bonds. Fluorinated alcohols can readily be accessed by the removal of auxiliaries, and significantly expands the synthetic prospect of the present procedure.

The novel N-(4-bromobenzylidene)-2,3-dihydrobenzo[b][1,4]dioxin-6-amine compound is designed and subjected to structural studies, inhibition of sPLA2, and molecular docking. The compound was synthesized by condensation of 1,4-benzodioxan-6-amine and 4-bromobenzaldehyde and characterized by various spectral techniques. Single crystal X-ray diffraction analysis confirmed the 3D molecular structure and established the different intermolecular interactions responsible for the crystal structure stability. Further synthesized compound was evaluated for anti-inflammatory activity using sPLA2 inhibition by indirect hemolytic assay. The compound showed good inhibition against sPLA2 enzyme compared with standard diclofenac, which is validated by molecular docking with a ?7.60 kcal/mol docking score.

Fluoro- or trifluoromethyl-substituted benzyl and phenethyl alcohols: Substrates for metal-mediated site-selective functionalization

It was possible to functionalize the three fluorobenzyl alcohols and the three 2-(fluorophenyl)ethanols by metalation and subsequent carboxylation, the prototype electrophilic trapping reaction. Triisopropylsilyl (TIPS) outperformed methoxymethyl (MOM) as an O-protective group making seven new fluorobenzoic acids accessible in 63% average yield. Moreover, the TIPS group tolerates weakly basic and acidic media and, therefore, may facilitate further structural elaboration. The unprotected alcohols reacted more sluggishly and were unable to provide two of the targeted products (acids 1 and 2). The yield averaged only 46% in the five other cases (acids 3-7). The direct metalation of fluorinated benzyl and phenethyl alcohols remains nevertheless an attractive option because of its operational simplicity. All three (trifluoromethyl)benzyl alcohols and two of the three (trifluoromethyl)phenethyl alcohol isomers were successfully submitted to the metalation/functionalization sequence. These five starting materials gave rise to a total of nine new benzoic acids or lactones (compounds 8-14 and 17-18). Despite the poor yields (31% on average), the organometallic methods employed are, in general, extremely selective, economical and easy to perform.

Palladium-Catalyzed Decarbonylative Trifluoromethylation of Acid Fluorides

While acid fluorides can readily be made from widely available or biomass-feedstock-derived carboxylic acids, their use as functional groups in metal-catalyzed cross-coupling reactions is rare. This report presents the first demonstration of Pd-catalyzed decarbonylative functionalization of acid fluorides to yield trifluoromethyl arenes (ArCF3). The strategy relies on a Pd/Xantphos catalytic system and the supply of fluoride for transmetalation through intramolecular redistribution to the the Pd center. This strategy eliminated the need for exogenous and detrimental fluoride additives and allows Xantphos to be used in catalytic trifluoromethylations for the first time. Our experimental and computational mechanistic data support a sequence in which transmetalation by R3SiCF3 occurs prior to decarbonylation.

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