A facile and practical copper diacetate mediated, ligand free C-N cross coupling of trivalent organobismuth compounds with amines and N-heteroarenes

In present work, an efficient Cu(OAc)2¡¤H2O catalyzed protocol in the absence of any additional ligand has been developed for the N-arylation of amines and nitrogen containing heterocycles using trivalent organobismuth reagents under mild conditions. This protocol tolerates a variety of functional groups on amines and the organobismuth reagent with a high degree of chemoselectivity.

Sodium borohydride reduction of aldehydes catalyzed by an oxovanadium(IV) Schiff base complex encapsulated in the nanocavity of zeolite-Y

Selective reduction of a wide range of aromatic and aliphatic aldehydes to the corresponding alcohols with NaBH4 was achieved in the presence of an oxovanadium(IV) Schiff base complex encapsulated in the nanopores of zeolite Y (VOL-Y). For most of the aldehydes, a conversion of 100% was observed after less than 5 min. High chemoselectivity of the reduction for aldehydes over ketones was verified by a competitive reduction between 4-methylbenzaldehyde and acetophenone.

An Orally Bioavailable, Indole-3-glyoxylamide Based Series of Tubulin Polymerization Inhibitors Showing Tumor Growth Inhibition in a Mouse Xenograft Model of Head and Neck Cancer

A number of indole-3-glyoxylamides have previously been reported as tubulin polymerization inhibitors, although none has yet been successfully developed clinically. We report here a new series of related compounds, modified according to a strategy of reducing aromatic ring count and introducing a greater degree of saturation, which retain potent tubulin polymerization activity but with a distinct SAR from previously documented libraries. A subset of active compounds from the reported series is shown to interact with tubulin at the colchicine binding site, disrupt the cellular microtubule network, and exert a cytotoxic effect against multiple cancer cell lines. Two compounds demonstrated significant tumor growth inhibition in a mouse xenograft model of head and neck cancer, a type of the disease which often proves resistant to chemotherapy, supporting further development of the current series as potential new therapeutics.

Palladium-Catalyzed Oxidative Sulfenylation of Indoles and Related Electron-Rich Heteroarenes with Aryl Boronic Acids and Elemental Sulfur

An efficient and convenient palladium-catalyzed C-H bond oxidative sulfenylation of indoles and related electron-rich heteroarenes with aryl boronic acids and elemental sulfur has been described. This procedure provides a useful and direct approach for the assembly of a wide range of structurally diverse 3-sulfenylheteroarenes with moderate to excellent yields from simple and readily available starting materials. Moreover, this synthetic protocol is suitable for N-protected and unprotected indoles. Notably, the construction of two C-S bonds in one step was also achieved in this transformation.

Transition metal-free sodium borohydride promoted controlled hydration of nitriles to amides

A transition metal-free process, promoted by sodium borohydride, has been developed for convenient and selective hydration of nitriles to corresponding amides. The present process converts the aromatic, aliphatic, and heteroaromatic nitriles with wide functional group tolerance. The regioselective hydration of one nitrile moiety in the presence of an other nitrile group makes high impact in the present protocol.

Validation of an Analytical Method to Determine Melatonin and Compounds Related to l-Tryptophan Metabolism Using UHPLC/HRMS

Melatonin is a bioactive compound that is present in wines because of the metabolism of l-tryptophan by yeasts. Even though the complete pathway of synthesis is not well elucidated, certain related indolic compounds might be involved in it. Consequently, their determination is a matter of interest. On one hand, their formation during fermentation might be related to a specific role for yeasts metabolism, not known so far. On the other hand, the synthesis by yeasts of bioactive compounds with putative health benefits for consumers, such as melatonin or serotonin, is a relevant matter. This paper aims to develop and validate an analytical method by ultra high-performance liquid chromatography coupled to high-resolution mass spectrometry (UHPLC/HRMS) to monitor both melatonin and related indolic compounds, in order to decrease their detection limits and make it possible to assess their occurrence in culture medium and fermented products. In addition, the other objective is to evaluate the production of these compounds by a commercial Saccharomyces cerevisiae used to make white wines. Diminishing the limit of detection below 0.5?ng?mL?1 for all compounds under study is an achievement of this work. Furthermore, the strain under study (AROMA WHITE) has been found to synthesise melatonin and related compounds as serotonin. Additionally, the evolution of these compounds over time may contribute to understanding the role that they play in yeast metabolism.

Synthesis of Tetrahydroisoquinolines through an Iron-Catalyzed Cascade: Tandem Alcohol Substitution and Hydroamination

Rapid assembly of saturated nitrogen heterocycles – the synthetically more challenging variants of their aromatic relatives – can expedite the synthesis of biologically relevant molecules. Starting from a benzylic alcohol tethered to an unactivated alkene, an iron-catalyzed tandem alcohol substitution and hydroamination provides access to tetrahydroisoquinolines in a single synthetic step. Using a mild iron-based catalyst, the combination of these operations forms two carbon-nitrogen bonds and provides a unique annulation strategy to access this valuable core.
