- Synthesis of aryloxyacetonitriles based on arylboronic acids with 2-bromoacetonitrile
-
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.

- Perfluorobutyl iodide-assisted direct cyanomethylation of azoles and phenols with acetonitrile
-
A perfluorobutyl iodide-assisted transition-metal-free cyanomethylation of azoles and phenols with acetonitrile in the presence of NaH has been developed. The reaction proceeded smoothly under mild reaction conditions to give the cyanomethylated products in moderate to high yields. A mechanism involving the cyanomethyl radical through C-H bond cleavage in acetonitrile was proposed. This journal is

- Combinatorial synthesis and in vitro evaluation of a biaryl hydroxyketone library as antivirulence agents against mrsa
-
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.
