Direct Regioselective C-H Cyanation of Purines

Molecules, 2023
A direct regioselective C-H cyanation of purines was developed through a sequential triflic anhydride activation, nucleophilic cyanation with TMSCN, followed by a process of base-mediated elimination of triflous acid (CF3SO2H).

Synthesis, characterization and study of antibacterial activity of some novel tetrazole derivatives

Orbital: The Electronic Journal of Chemistry, 2011
This work aims at synthesizing novel tetrazole derivatives from phenothiazine. Phenothiazine is first converted into corresponding nitrile by reacting it with aldehyde, sodium metabisulphite and sodium cyanide.

Synthesis of Simplified Azasordarin Analogs as Potential Antifungal Agents [PDF]

, 2019
A new series of simplified azasordarin analogs was synthesized using as key steps a Diels–Alder reaction to generate a highly substituted bicyclo[2.2.1]heptane core, followed by a subsequent nitrile alkylation.

Synthesis of Highly Substituted Oxazoles through Iodine(III)-Mediated Reactions of Ketones with Nitriles

Molecules, 2012
In the presence of trifluoromethanesulfonic acid (TfOH) or bis(trifluoromethane-sulfonyl)imide (Tf2NH), iodosobenzene (PhI=O) efficiently promoted the reactions of dicarbonyl compounds as well as monocarbonyl compounds with nitriles to give 2,4 ...

Process Development of the Copper(II)‐Catalyzed Dehydration of a Chiral Aldoxime and Rational Selection of the Co‐Substrate

ChemistryOpen, 2022
The access towards chiral nitriles remains crucial in the synthesis of several pharmaceuticals. One approach is based on metal‐catalyzed dehydration of chiral aldoximes, which are generated from chiral pool‐derived aldehydes as substrates, and the use of

Optimized intermolecular potential for nitriles based on Anisotropic United Atoms model [PDF]

, 2008
An extension of the Anisotropic United Atoms intermolecular potential model is proposed for nitriles. The electrostatic part of the intermolecular potential is calculated using atomic charges obtained by a simple Mulliken population analysis.

Characterization of a recombinant β-glucosidase of GH3 family from glucosinolate-metabolizing human gut bacterium Enterococcus casseliflavus CP1 for nitrile production [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2020
A recombinant β-glucosidase human gut bacterium capable of nitrile production from desulfo-glucosinolates was studied. The bgl4 gene (2,151 bp) from Enterococcus casseliflavus CP1 was cloned and overexpressed in Escherichia coli BL21(DE3) at 25 °C for ...

Swelling Properties of Nitrile-butadiene Rubber with Different Acrylonitrile Content in Isopropyl Nitrate

Chemical Engineering Transactions, 2017
Nitrile-butadiene rubber is the sealing material of isopropyl nitrate; however, leakage or vaporization phenomena frequently occur. In order to analyze the causes of leakage and volatilization and study on the various properties of nitrile-butadiene ...
