The Rh-catalyzed C-H alkylation of benzylamine derivatives with unactivated 1-alkenes that proceeds via a picolinamide directing group is reported. The crucial role of an acid additive in this transformation is confirmed. Aromatic acids showed high linear selectivity, and aliphatic acids provided branched alkylation products as the major product. The reaction has a broad scope for benzylamines and alkenes. Deuterium labeling experiments suggest that a Rh-carbene intermediate is involved in the case of linear product formation. A different reaction pathway, however, appears to be involved in the case of branched alkylation products, and this pathway also appeared to be a minor pathway in linear-selective reactions.

The first intermolecular carbonyl arylations via transfer hydrogenative reductive coupling are described. Using rhodium catalysts modified by (Bu2PMe)-Bu-t, sodium formate-mediated reductive coupling of aryl iodides with aldehydes occurs in a chemoselective fashion in the presence of protic functional groups and lower halides. This work expands the emerging paradigm of transfer hydrogenative coupling as an alternative to preformed carbanions or metallic reductants in C=X addition.

Cyclin-dependent kinases play significant roles in cell cycle progression and are promising targets for cancer therapy. However, most potent CDK inhibitors lack the balance between efficacy and safety because of poor selectivity. Given the roles of CDK2 in tumorigenesis, selective CDK2 inhibition may provide therapeutic benefits against certain cancer. In this study, a series of 4-benzoylamino-1H-pyrazole-3-carboxamide derivatives were designed, synthesized, and evaluated. The most selective compound DC-K2in212 in this series exhibited high potency towards CDK2 and had effective anti-proliferative activity against A2058 melanoma cell line and MV4-11 leukemia cell line while exhibiting low toxic effect on human normal cell lines MRC5 and LX2. The molecular modeling illustrated that compound DC-K2in212 had the similar binding mode with CDK2 as C-73, the most selective CDK2 inhibitor reported so far, which might account for selectivity against CDK2 over CDK1. Further biological studies revealed that compound DC-K2in212 suppressed CDK2-associated downstream signaling pathway, blocked cell cycle progression, and induced cellular apoptosis. Therefore, compound DC-K2in212 could serve as a potential CDK2 inhibitor for further development. (c) 2021 Elsevier Masson SAS. All rights reserved.

A linear synthesis of o-terphenyl derivatives has been delineated using ring closing metathesis (RCM) as the key step. In this approach, benzil derivatives upon allyl Grignard addition provides diphenyl-1,2-diallyl dihydroxy derivatives which undergo ring closing metathesis to afford tetrahydro terphenyl derivatives. Aromatization-driven dehydration then leads to a diverse set of electron rich and electron deficient o-terphenyls. Furthermore, oxidative coupling of electron rich o-terphenyls provides the corresponding triphenylene derivatives.

Eleven new tetrahydrobenzo[b]pyran derivatives were synthesized via a three component reaction of different aromatic aldehydes, methyl cyanoacetate and 1,3-cyclohexadione, with water as solvent under catalyst-free microwave irradiation. The structures of all the new molecules were well analysed and their structures established by using various spectral techniques (H-1 NMR, C-13 NMR, N-15 NMR and HRMS). Various advantages of reported protocol are the ease of preparation, short reaction times (10 min), aqueous solvent and excellent yields (89-98%). Additionally, this method provides a clean access to the desired products by simple workup.

Due to its function as a vasopressor, the vicinal amino alcohol methoxamine is a potential candidate for the treatment of hypotension and incontinence or has applications in ophthalmology. In this study, a biocatalytic method was developed to produce each of the four stereoisomers of methoxamine in a sequential 1-pot 2-step cascade reaction, starting from readily available pyruvate and 2,5-dimethoxy-enzaldehyde without intermediate isolation. All four isomers are accessible with high conversions and very good stereoselectivities through the modular combination of carboligases and transaminases with high stereoselectivities. The development of these cascades was made possible, among other factors, by the integration of a recently engineered triple variant of the pyruvate decarboxylase from Acetobacter pasteurianus (ApPDC-E469G-468A-W543F), which provided access to the intermediate (S)-1-hydroxy-1-(2,5-dimethoxyphenyl)propan-2-one with a high enantiomeric excess of 98%. For the amination of these sterically demanding 2-hydroxy ketones, Bacillus megaterium transaminase in particular has proven to be a highly active and selective catalyst. All four methoxamine stereoisomers were achieved with isomeric contents between 94% and 99% and total conversions of both steps between 59% and 80%. Separation of each isomer without derivatizing was possible using supercritical fluid chomratographie with two columns connected in a row. A preparative scale (75 mL) of the 1-pot 2-step cascade to (1S,2R)-methoxamine including nonoptimized product isolation showed 85 mg HCl salt (46% isolated yield) with 94% purity (NMR) and an isomeric content of 98%.

The Pomeranz-Fritsch reaction and its Schlittler-Muller modification were successfully applied in the Ugi postcyclization strategy by using orthogonally protected aminoacetaldehyde diethyl acetal and complementary electron rich building blocks. Several scaffolds, including isoquinolines, carboline, alkaloid-like tetrazole-fused tetracyclic compounds, and benzo[d]azepinone scaffolds, were synthesized in generally moderate to good yield. All our syntheses provide a short MCR-based sequence to novel or otherwise difficult to access scaffolds. Hence, we foresee multiple applications of these synthesis technologies.

Several pyrrolo[2,3-b]pyridine-based B-RAF inhibitors are well known and some of them are currently FDA approved as anticancer agents. Based on the structure of these FDA approved B-V600E-RAF inhibitors, two series of pyrrolo[2,3-b]pyridine scaffold were designed and synthesized in attempt to develop new potent B-V600E-RAF inhibitors. The 38 synthesized compounds were biologically evaluated for their B-V600E-RAF inhibitory effect at single dose (10 mu M). Compounds with high percent inhibition were tested to determine their IC50 over (V600E)BRAF. Compounds 34e and 35 showed the highest inhibitory effect with IC50 values of 0.085 mu M and 0.080 mu M, respectively. Headed for excessive biological evaluation, the synthesized derivatives were tested over sixty diverse human cancer cell lines. Only compound 35 emerged as a potent cytotoxic agent against different panel of human cancer cell lines.
