An acid-free N-nitrosation/nitration of the N-H bonds in secondary amines with Fe(NO3)(3)center dot 9H(2)O as the nitroso/nitro source through an electrocatalyzed radical coupling reaction was developed. Cyclic aliphatic amines and N-heteroaromatic compounds were N-nitrosated and N-nitrated, respectively, under mild conditions. Control and competition experiments, as well as kinetic studies, demonstrate that N-nitrosation and N-nitration involve two different radical reaction pathways involving N+ and N-center dot radicals. Moreover, the electrocatalysis method enables the preferential activation of the N-H bond over the electrode and thus provides high selectivity for specific N atoms. Finally, this strategy exhibits a broad scope and provides a green and straightforward approach to generate useful N-nitroso/nitro compounds in good yields.

Compared to the abundance of methodologies accessing 1-substituted and 1,3-disubstuted bicyclo[1.1.1] pentanes (BCPs), the synthetic accessibility of BCPs with substitutions at the methylene position has been limited. Herein, we report a selective synthesis of 1-dialkylamino-2-alkylbicyclo[1.1.1]pentanes from prefunctionalized starting materials. We also achieved further functionalizations of these 1,2-disubstituted BCPs and developed a synthesis of these compounds with minimum necessity of chromatographic purifications starting from 1,3-dichloroacetone. Finally, we also detailed the synthesis of a 1,2,3-trisubstituted BCP analogue.

We report on the discovery of norbornyl moiety as a novel structural motif for cyclin-dependent kinase 2 (CDK2) inhibitors which was identified by screening a carbocyclic nucleoside analogue library. Three micromolar hits were expanded by the use of medicinal chemistry methods into a series of 16 novel compounds. They had prevailingly micromolar activities against CDK2 and the best compound of the series attained IC(50)of 190 nM. The binding modes were explored in molecular details by modeling and docking. Quantum mechanics-based scoring was used to rationalize the affinities. In conclusion, the discovered 9-hydroxymethylnorbornyl moiety was shown by joint experimental-theoretical efforts to be able to serve as a novel substituent for CDK2 inhibitors. This finding opens door to the exploration of chemical space towards more effective derivatives targeting this important class of protein kinases.

Sulfoximines and sulfonimidamides are promising compounds for medicinal and agrochemistry. As monoaza analogues of sulfones and sulfonamides, respectively, they combine good physicochemical properties, high stability, and the ability to build complexity from a three-dimensional core. However, a lack of quick and efficient methods to prepare these compounds has hindered their uptake in molecule discovery programmes. Herein, we describe a unified, one-pot approach to both sulfoximines and sulfonimidamides, which exploits the high electrophilicity of sulfinyl nitrenes. We generate these rare reactive intermediates from a novel sulfinylhydroxylamine (R-O-N=S=O) reagent through an N-O bond fragmentation process. Combining sulfinyl nitrenes with carbon and nitrogen nucleophiles enables the synthesis of sulfoximines and sulfonimidamides in a reaction time of just 15 min. Alkyl, (hetero)aryl, and alkenyl organometallic reagents can all be used as the first or second component in the reaction, while primary and secondary amines, and anilines, all react with high efficiency as the second nucleophile. The tolerance of the reaction to steric and electronic factors has allowed for the synthesis of the most diverse set of sulfoximines and sulfonimidamides yet described. Experimental and computational investigations support the intermediacy of sulfinyl nitrenes, with nitrene formation proceeding via a transient triplet intermediate before reaching a planar singlet species.

In the presence of a bimetallic Pd/Cu system with 1,10-phenanthroline as the ligand and either air or N-methylmorpholine N-oxide as the oxidant, electron-deficient benzoic acids undergo oxidative decarboxylative coupling with unprotected amines. This operationally simple aniline synthesis is widely applicable with respect to the amine and gives good yields, even on multigram scale. The orthogonality of this reaction to other Pd-catalyzed cross-couplings allows the concise synthesis of multisubstituted arenes by sequential C-C, C-Cl, and C-N functionalizations. Mechanistic investigations suggest the intermediacy of a hypervalent Pd species.

Rho-associated serine/threonine kinases (ROCKs) are principal regulators of the actin cytoskeleton that regulate the contractility, shape, motility, and invasion of cells. We explored the relationships between structure and anti-ROCK2 activity in a group of purine derivatives substituted at the C6 atom by piperidin-1-yl or azepan-1-yl groups. Structure-activity relationship (SAR) analyses suggested that anti-ROCK activity is retained, and may be further increased, by substitution of the parent compounds at the C2 atom or by expansion of the C6 side chain. These inhibitors of ROCK can reach effective concentrations within cells, as demonstrated by a decrease in phosphorylation of the ROCK target MLC, and by inhibition of the ROCK-dependent invasion of melanoma cells in the collagen matrix. Our study may be useful for further optimization of C6-substituted purine inhibitors of ROCKs and of other sensitive kinases identified by the screening of a broad panel of protein kinases.

The cascade amination/cyclization ofN-arylacrylamides with alkyl amines under visible-light photoredox catalysis is realized via intermediacy of aminium radicals. The aminium radicals are generated by a two-step sequence which involves N-chlorination of alkyl amines and subsequent reductive N-Cl cleavage. This method provides a convenient access to aminated oxindoles.
