We developed a mild aromatic halogenation reaction using a combination of N-halosuccinimide and PhSSiMe3 or PhSSPh. Less reactive aromatic compounds, such as methyl 4-methoxybenzoate, were brominated with PhSSiMe3 or PhSSPh and N-bromosuccinimide in high yields. No reaction was observed in the absence of PhSSiMe3 or PhSSPh. This method is also applicable to chlorination reactions using N-chlorosuccinimide and PhSSPh.

An iron (II) tetramethylated tetrapyridinoporphyrazine (FeII(2,3-tmtppa)) grafted onto sulfonated SBA-15 (SBA15@n-Pr-SO3@Fetmtppa)) has been synthesized. The catalyst was characterized using X-ray diffraction, nitrogen adsorption?desorption measurements, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy, thermogravimetric analysis and scanning electron microscopy. XRD, XPS and ICP analyses confirmed the incorporation of iron (II) ion onto the surface of functionalized support. TGA and BET diagrams, FESEM and TEM images showed the grafting of (FeII(2,3-tmtppa)) on SBA-15 with mesoporous structure and ordered channels after immobilization process. This catalyst is able to perform C-H oxidation reaction of alkanes including toluene and ethylbenzene derivatives in the presence of molecular oxygen under the mild reaction in water. The hot filtration and reusability tests of the catalyst were studied which showed that the C-H activation reaction proceeds via heterogeneous pathway and catalyst is recoverable for at least 5 times.

Our group recently reported the use of [(DPEPhos)(bcp)Cu]PF6 as a general copper-based photoredox catalyst which proved efficient to promote the activation of a broad variety of organic halides, including unactivated ones. These can then participate in various radical transformations such as reduction and cyclization reactions, as well as in the direct arylation of several (hetero)arenes. These transformations provide a straightforward access to a range of small molecules of interest in synthetic chemistry, as well as to biologically active natural products. Altogether, [(DPEPhos)(bcp)Cu]PF6 acts as a convenient photoredox catalyst which appears to be an attractive, cheap and complementary alternative to the state-of-the-art iridium- and ruthenium-based photoredox catalysts. Here, we report a detailed protocol for the synthesis of [(DPEPhos)(bcp)Cu]PF6, as well as NMR and spectroscopic characterizations, and we illustrate its use in synthetic chemistry for the direct arylation of (hetero)arenes and radical cyclization of organic halides. In particular, the direct arylation of N-methylpyrrole with 4-iodobenzonitrile to afford 4-(1-methyl-1H-pyrrol-2-yl)benzonitrile and the radical cyclization of N-benzoyl-N-[(2-iodoquinolin-3-yl)methyl]cyanamide to afford natural product luotonin A are detailed. The scope and limitations of this copper-based photoredox catalyst are also briefly discussed.

Herein we report the discovery of pyrazolocarboxamides as novel, potent, and kinase selective inhibitors of receptor interacting protein 2 kinase (RIP2). Fragment based screening and design principles led to the identification of the inhibitor series, and X-ray crystallography was used to inform key structural changes. Through key substitutions about the N1 and C5 N positions on the pyrazole ring significant kinase selectivity and potency were achieved. Bridged bicyclic pyrazolocarboxamide 11 represents a selective and potent inhibitor of RIP2 and will allow for a more detailed investigation of RIP2 inhibition as a therapeutic target for autoinflammatory disorders.

The recent interest in bio-oils combustion and the key role of mono-aromatic hydrocarbons (MAHs) in existing kinetic frameworks, both in terms of poly-aromatic hydrocarbons growth and surrogate fuels formulation, motivates the current systematic theoretical investigation of one of the relevant reaction classes in MAHs pyrolysis and oxidation:ipsosubstitution by hydrogen. State-of-the-art theoretical methods and protocols implemented in automatized computational routines allowed to investigate 14 different potential energy surfaces involving MAHs with hydroxy and methyl single (phenol and toluene) and double (o-,m-,p-C6H4(OH)(2),o-,m-,p-CH3C6H4OH, ando-,m-,p-C6H4(CH3)(2)) substituents, providing rate constants for direct implementation in existing kinetic models. The accuracy of the adopted theoretical method was validated by comparison of the computed rate constants with the available literature data. Systematic trends in energy barriers, pre-exponential factors, and temperature dependence of the Arrhenius parameters were found, encouraging the formulation of rate rules for ipsosubstitutions on MAHs. The rules here proposed allow to extrapolate from a reference system the necessary activation energy and pre-exponential factor corrections for a large number of reactions from a limited set of electronic structure calculations. We were able to estimate rate constants for other 63 ipsoaddition-elimination reactions on di-substituted MAHs, reporting in total 75 rate constants for ipsosubstitution reactionso-,m-,p-R ‘ C6H4R + -> C6H5R + ‘, with R,R ‘ = OH/CH3/OCH3/CHO/C2H5, in the 300-2000 K range. Additional calculations performed for validation showed that the proposed rate rules are in excellent agreement with the rate constants calculated using the full computational protocol in the 500-2000 K range, generally with errors below 20%, increasing up to 40% in a few cases. The main results of this work are the successful application of automatized electronic structure calculations for the derivation of accurate rate constants for ipsosubstitution reactions on MAHs, and an efficient and innovative approach for rate rules formulation for this reaction class.

The chlorination of a bioactive compound can change its physiological properties and improve its pharmacokinetic and pharmacological profiles. It therefore has been an important strategy for drug discovery and development. However, the direct aromatic chlorination of complex bioactive molecules is too difficult to be practical. In fact, many functional groups such as hydroxyls, amines, amides or carboxylic acids may strongly restrain the reactivity of Cl+ by forming a halogen bond. Here we report a highly efficient aromatic chlorination of arenes that is catalysed by dimethyl sulfoxide with N-chlorosuccinimide as the chloro source. The mild conditions, easy-availability and stability of the catalyst and reagents, as well as good functional-group tolerance, showed the approach to be a versatile protocol for the late-stage aromatic chlorination of complex natural products, drugs and peptides. The multi-gram experiment and low-cost of N-chlorosuccinimide and dimethyl sulfoxide shows great potential for drug discovery and development in industrial applications. Late-stage aromatic chlorination of active pharmaceutical ingredients has enormous potential in drug discovery yet still features limited applicability due to issues of functional-group tolerance. Now, dimethyl sulfoxide is reported as catalyst for the chlorination of a diverse family of bioactive molecules in combination with N-chlorosuccinimide.

A diverse range of ureas, N-acylureas, carbamates, and thiocarbamates has been synthesized in good to excellent yields by reacting N-acylbenzotriazoles individually with amines or amides or phenols or thiols in the presence of diphenylphosphoryl azide (DPPA) as a suitable azide donor in anhydrous toluene at 110 degrees C for 3-4 hours. In this route, DPPA was found to be a good alternative to trimethylsilyl azide and sodium azide for the azide donor in Curtius degradation. The high reaction yields, one-pot and metal-free conditions, straightforward nature, easy handling, use of readily available reagents, and in many cases avoidance of column chromatography are the notable features of the devised protocol.
