Picolinamide group assisted sp(3) C-H bond oxidation of methylene groups to the corresponding carbonyl compounds has been achieved by using simple bottle ferrocene as catalyst and Cu(OAc)(2) or tert-butyl peroxybenzoate (TBPB) as oxidant under mild conditions. This method is applicable for picolinamide bound organic as well as organometallic compounds with yields in the range of 46-82%. Control experiments and mechanistic studies indicate that a radical mechanism is responsible for these oxidative transformations in which ferrocene acts as a catalyst.

A magnetic catalyst is synthesized through growth of dendrimer of generation 3 (G3) on the surface of halloysite (Hal) nanotubes followed by decoration of dendrimer terminal groups with ionic liquid (IL) and incorporation of Fe species. The structure of the catalyst was confirmed by using several characterization techniques. Moreover, the catalytic activity of the catalyst for oxidation of benzaldehydes to the corresponding benzoic acids in the presence of hydrogen peroxide was investigated. Notably, to improve the yield of the reaction, beta-cyclodextrin (beta-CD) was employed as phase transfer agent. The contribution of dendrimer and IL to the catalysis was confirmed by comparing the catalytic activity of the catalyst with that of control the catalysts (the catalyst without IL, Fe species and dendrimer). Furthermore, the effect of dendrimer generation was elucidated by comparing the catalytic activities of the catalysts prepared by growth of dendrimers of G1, G2 and G3 on Hal. Studying the recyclability of the catalyst, it was found that the catalyst could be recovered and recycled for several reaction times with slight loss of leaching of Fe species.

Endeavor to discover biorational natural products-based insecticides, two series (27) of novel 9R/S-acyloxy derivatives of cinchonidine and cinchonine were prepared and assessed for their insecticidal activity against Mythimna separata in vivo by the leaf-dipping method at 1 mg/mL. Among all the compounds, especially derivatives 6l and 6o exhibited the best insecticidal activity with final mortality rates of 75.0% and 71.4%, respectively. Overall, a free 9-hydroxyl group is not a prerequisite for insecticidal activity and C9-substitution is well tolerated; the configuration of C8/9 position is important for insecticidal activity, and 9S-configuration is optimal; 6′-OCH3 moiety is not necessary, removal of it is also acceptable.

The ability to selectively forge C-heteroatom bonds by C-F scission is typically accomplished by metal catalysts, specialized ligands and/or harsh reaction conditions. Described herein is a base-mediated defluorosilylation of unactivated C(sp(2))-F and C(sp(3))-F bonds that obviates the need for metal catalysts. This protocol is characterized by its simplicity, mild reaction conditions, and wide scope, even within the context of late-stage functionalization, constituting a complementary approach to existing C-Si bond-forming protocols.

FLT3 mutation is among the most common genetic mutations in acute myeloid leukemia (AML), which is also related with poor overall survival and refractory in AML patients. Recently, FLT3 inhibitors have been approved for AML therapy. Herein, a series of new compounds with pyrazole amine scaffold was discovered, which showed potent inhibitory activity against FLT3-ITD and significant selectivity against both FLT3-ITD and AML cells expressing FLT3-ITD. Compound 46, possessing the most promising cellular activity, blocked the autophosphorylation of FLT3 pathway in MV4-11 cell line. Furthermore, the apoptosis and downregulation of P-STAT5 were also observed in tumor cells extracted from the MV411 cell xenografts model upon compound 46 treatment. Compound 46 was also metabolically stable in vitro and suppressed tumor growth significantly in MV4-11 xenografts model in vivo. Compound 46 showed no toxicity to the viscera of mice and caused no decrease in body weight of mice. In conclusion, the results of this study could provide valuable insights into discovery of new FLT3 inhibitors, and compound 46 was worthy of further development as potential drug candidate to treat AML (C) 2019 Elsevier Masson SAS.

A catalyst-free and solvent-free method for the hydroboration of a variety of carboxylic acids with pinacolborane was developed. The hydroboration of various aromatic and aliphatic carboxylic acids as well as dicarboxylic acids with HBpin could be completed within 6 h at room temperature or within 1 h at 60 degrees C to give the products in quantitative yields under neat conditions without the need for any solvent or metal catalyst. The possible reaction mechanism was investigated in detail based on the corresponding DFT calculations and the stoichiometric reaction of acetic acid with different equivalents of HBpin (at room temperature and 0 degrees C) and it revealed the stepwise nature of the protocol.

Chemo selective reduction of a wide range of aromatic nitro compound has been performed by using inexpensive Zn powder and CuSO4 system in water medium at room temperature. This system has high tolerance to other highly reducible groups present in nitro substance along with high conversation and selectivity. This chemo-selective reduction also provides a facile root for the synthesis of other industrially important fine chemicals or biologically important compounds where other highly reducible groups are present in close proximity to the targeted nitro groups.

Calcium dependent protein kinase 1 (CDPK1) is an essential Ser/Thr kinase that controls invasion and egress by the protozoan parasite Toxoplasma gondii. The Gly gatekeeper of CDPK1 makes it exquisitely sensitive to inhibition by small molecule 1H-pyrazolo[3,4-d]pyrimidine-4-amine (PP) compounds that are bulky ATP mimetics. Here we rationally designed, synthesized, and tested a series of novel PP analogs that were evaluated for inhibition of CDPK1 enzyme activity in vitro and parasite growth in cell culture. Optimal substitution on the PP scaffold included 2-pyridyl ethers directed into the hydrophobic pocket and small carbocyclic rings accessing the ribose-binding pocket. Further optimization of the series led to identification of the lead compound 3a that displayed excellent potency, selectivity, safety profile, and efficacy in vivo. The results of these studies provide a foundation for further work to optimize CDPK1 inhibitors for the treatment of acute and chronic toxoplasmosis.

The first asymmetric Pd-II-catalyzed aminofluorination of unactivated alkenes using chiral quinoline-oxazolines (Quox) as ligands has been developed. This reaction provides easy access to a wide array of enantiomerically enriched beta-fluoropiperidines in good yields and with excellent enantioselectivity. Notably, Et4NF.3 HF as a readily accessible nucleophilic fluoride source was found to play an essential role in the enantioselective control, and CsOCF3 also acts a key additive to improve the excellent ee value of products.

A large family of phosphite-thioether/selenoether ligands has been easily prepared from accessible L-(+)-tartaric acid and D-(+)-mannitol and applied in the M-catalyzed (M=Ir, Rh) asymmetric hydrogenation of a broad number of substrates (46 in total). Its highly modular architecture has been crucial to maximize the catalytic performance. Improving most of the reported approaches, this ligand family presents a broad substrate scope. By selecting the ligand parameters high enantioselectivities (ee’s up to 99 %) have therefore been achieved in a broad range of both, functionalized and unfunctionalized substrates. Interestingly, both enantiomers of the hydrogenation products can be usually achieved by changing the ligand parameters.
