A synergistic catalytic method combining photoredox catalysis, hydrogen-atom transfer, and proton-reduction catalysis for the dehydrogenative silylation of alkenes was developed. With this approach, a highly concise route to substituted allylsilanes has been achieved under very mild reaction conditions without using oxidants. This transformation features good to excellent yields, operational simplicity, and high atom economy. Based on control experiments, a possible reaction mechanism is proposed.

A simple and facile copper(II) mediated protocol for C-8 amination of 1-naphthylamide derivatives is reported here. Picolinamide and its derivatives were used as a bidentate directing group for the C-8 amination reaction. Various substituted naphthylamide derivatives with numerous cyclic and acyclic amines proceed in good yields under mild conditions. Air was used solely as an oxidant. (C) 2021 Elsevier Ltd.

A simple and efficient Fe-catalyzed regioselective alkylation of 1,4-quinones and coumarins, using functionalized alkyl bromides as alkylating reagents, has been developed. The reaction proceeds under mild conditions with the addition of alkyl bromides to a wide range of 1,4-quinone and coumarin derivatives with a broad substrate scope and wide functional group tolerance to provide the products in good yields. Further application of these strategies could be extended to important biologically active antimalarial lead drugs, such as plasmodione on a gram scale in a single step for medicinal purposes.

A Cu-catalyzed dearomative amination of simple phenols with O-benzoylhydroxylamines (R’RN-OBz) to synthesize alpha-aminocyclohexa-2,4-dienones is reported. This intermolecular transformation occurs exclusively at the position ortho to the hydroxyl group, providing a convenient method to synthesize the desired products in high yields. The reaction proceeds under mild conditions and tolerates a wide range of functional groups. Mechanistic studies indicate that this transformation proceeds via either (1) a single-electron transfer process involving attack of an N-centered radical onto the phenol or (2) a two-electron pathway involving addition of phenol to an electrophilic Cu-III-amino complex via an inner-sphere process.

Thienylzinc halides and related compounds prepared by deprotonation followed by transmetalation were used in copper-catalyzed amination using N-benzoyloxy secondary amines. By extending the reaction to 1,5-naphthyridine, it was showed that the competitive dimer formation observed in the case of thiophenes was linked with the low stability of some thienylamines rather than homocoupling. Interestingly, thienylzinc halides and related compounds prepared by transmetalation of thienylmagnesium halides, either prepared from their bromo-precursors or generated by deprotometalation, were satisfactorily employed in cobalt-catalyzed aminations. Finally, aminothiophenes were involved in copper-catalyzed mono- and di-N-arylations, affording differently substituted di- and triphenylamines.

Novel fluorinated 2-substituted 1,3-benzothiazin-4-ones were obtained through the addition of N-nucleophiles to ortho-fluorobenzoylisothiocyanates, followed by cyclization of fluorobenzoyl-thioureas. Synthetic approaches to original 2-cycloalkylimino- and 2-carbonylpiperazino- substituted benzothiazinones, bearing different number of fluorine atoms in the benzene ring have been found. 2-Ethoxycarbonylpiperazino-5-fluoro-1,3-benzothiazin-4-one proved to exhibit a high tuberculostatic activity in vitro (MIC 0.7 microgram/mL), thus indicating that a search of biologically active compounds in this family of heterocycles appears to be a reasonable approach.

Aberrant activation of FMS-like tyrosine receptor kinase 3 (FLT3) is implicated in the pathogenesis of acute myeloid leukemia (AML) in 20-30% of patients. In this study we identified a highly selective (phenylethenyl)quinazoline compound family as novel potent inhibitors of the FLT3-ITD and FLT3-D835Y kinases. Their prominent effects were confirmed by biochemical and cellular proliferation assays followed by mice xenograft studies. Our modelling experiments and the chemical structures of the compounds predict the possibility of covalent inhibition. The most effective compounds triggered apoptosis in FLT3-ITD AML cells but had either weak or no effect in FLT3-independent leukemic and non-leukemic cell lines. Our results strongly suggest that our compounds may become therapeutics in relapsing and refractory AML disease harboring various ITD and tyrosine kinase domain mutations, by their ability to overcome drug resistance.

Currently available drugs being used to treat leishmaniasis have several shortcomings, including high toxicity, drug administration that requires hospitalization, and the emergence of parasite resistance against clinically used drugs. As a result, there is a dire need for the development of new antileishmanial drugs that are safe, affordable, and efficient. In this study, two new series of synthesized quinazolinone derivatives were investigated as potential future antileishmanial agents, by assessing their activities against theLeishmania(L.)donovaniandL. majorspecies. The cytotoxicity profiles of these derivatives were assessed in vitro on Vero cells. The compounds were found to be safer and without any toxic activities against mammalian cells, compared to the reference drug, halofuginone, a clinical derivative of febrifugine. However, they had demonstrated poor antileishmanial growth inhibition efficacies. The two compounds that had been found the most active were the mono quinazolinone2dand the bisquinazolinone5bwith growth inhibitory efficacies of 35% and 29% for theL. majorandL. donovani9515 promastigotes, respectively. These outcomes had suggested structural redesign,inter aliathe inclusion of polar groups on the quinazolinone ring, to potentially generate novel quinazolinone derivatives, endowed with effective antileishmanial potential.

N-Boc deprotection (deBoc) is a common reaction in pharmaceutical research and development, as well as pharma manufacturing. Use of a catalyst lowers the required reaction temperature, and heterogeneous catalysts allow the reaction to be conducted in a continuous flow reactor with a low-boiling solvent, facilitating product separation and enhancing efficiency and productivity relative to a batch process. In this study, we explore the use of simple solid Bronsted acid catalysts to achieve continuous N-Boc deprotection of amines, without additional workup steps. Using THF as the solvent, H-BEA zeolite affords high yields of a variety of aromatic and aliphatic amines, often in residence times of less than a minute at 140 degrees C. The same catalyst/solvent combination is ineffective in batch conditions, due to the much lower temperature of refluxing THF. Boc-protected p-chloroaniline was deprotected with a throughput of 18 mmol p-chloroaniline per h per g(cat), sustained over 9 h. The active sites of the zeolite do not appear to be directly associated with the Al framework substitution in the micropores, since partially ion-exchanged Na/H-BEA shows activity similar to H-BEA. The strong Bronsted acid sites (framework [Si(OH)Al]), are likely poisoned by the amine product. Moderate Bronsted acid sites associated with silanol defects near Al on or near the external surface (and not susceptible to Na+-exchange) are presumably the active sites, since they are not poisoned even by more basic aliphatic amines.
