A new and efficient protocol for the synthesis of aryloxyacetonitriles based on arylboronic acids with 2-bromoacetonitrile has been developed using eco-friendly hydrogen peroxide as oxidant under metal-free conditions. This method is compatible with arylboronic acid attached sensitive substituent and obtains desired product in moderate to good yield.

A facile and highly efficient protocol for synthesis of new 5-substituted-1H-tetrazoles derivatives using copper-doped silica cuprous sulfate (CDSCS) is described. In this method, the cycloaddition reaction of sodium azide with structurally diverse nitriles involving bioactive N-heterocyclic cores exploiting CDSCS in refluxing H2O/i-PrOH (1:1, v/v) furnishes the corresponding 5-substituted-1H-tetrazoles in good to excellent yields (up to 93percent). The influence of parameters effective in progress of reaction including solvent type, temperature and catalyst was studied and discussed. In this protocol, CDSCS was proved to be an efficient heterogeneous nano-catalyst to easily achieve the new tetrazole derivatives. The advantages of CDSCS in current protocol known are its cheapness, thermal and chemical stability, ease of recyclability and reusability for several consecutive runs without significant decline in its reactivity.

Antibiotic resistance coupled with decreased development of new antibiotics necessitates the search for novel antibacterial agents. Antivirulence agents offer an alternative to conventional antibiotics. In this work, we report on a family of small-molecule antivirulence agents against methicillin-resistant Staphylococcus aureus (MRSA), the most widespread bacterial pathogen. Structure-activity relationship studies led to the development of a concise synthesis of a 148-member biarylhydroxyketone library. An acylation bond-forming process afforded resorcinols (1) and aryloxy acetonitriles (2) as synthons. A Lewis-acid-activated Friedel-Crafts' acylation step involving a nitrile functionality of 2 by ZnCl2, followed by nucleophilic attack by 1 was executed to obtain biaryl hydroxyketones in excellent yields. A large number of products crystallized. This strategy affords a range of biarylhydroxyketones in a single step. This is the first collective synthetic study documenting access to this class of compounds through a single synthetic operation. In vitro efficacy of compounds in this library was evaluated by a rabbit erythrocyte hemolysis assay. The most efficacious compound, 4f-12, inhibits hemolysis by 98.1 ± 0.1% compared to control in the absence of the compound.
