The aim of this study was to examine antibacterial and antifungal activity 2-amino-3-cyanopyridine derivatives against some microorganisms. investigated compounds 2, 4, 6 exhibit promising activities. high biological activities the indicated can be probably caused by simultaneous presence bromine atoms, nitro amino groups in molecules.
An Efficient Protocol for Synthesis of 2-amino-3cyanopyridine Derivatives using Nano-modified SBA-15
Condensation reaction of chalcones with malononitrile and ammonium acetate in the presence of the green nano-modified SBA-15 affords the corresponding 2-amino-3-cyanopyridine derivatives in excellent yield. This approaches claimed to be an environment friendly protocol as it afforded some advantages such as excellent yields and cleaner reaction.
Nicotinonitrile chromophores with two tunable functions, excellent photophysical properties and solvatochromic behaviour can be prepared quickly and efficiently by microwave-assisted tandem oxidation/Bohlmann-Rahtz heteroannulation followed by copper(I)-mediated N-arylation.
A simple and efficient procedure for the synthesis of 2-amino-3-cyanopyridines from aldehydes, ketones, malononitrile, and ammonium acetate via one-pot reaction is reported. Zinc zirconium phosphate (ZPZn) nanoparticles were used as a convenient and efficient catalyst for this multicomponent reaction (MCR) under solvent-free conditions, and fair to excellent yields were achieved. The catalyst w...

Assembly of Fe(II), 3-cyanopyridine and [Au(CN)2](-) affords, in one-pot reaction, three coordination polymers that represent a genuine example of supramolecular isomerism with strong influence in the spin crossover regime of the Fe(II) ions.
BACKGROUND Nitrilase is an important member of the nitrilase superfamiliy. It has attracted substantial interest from academia and industry for its function of converting nitriles directly into the corresponding carboxylic acids in recent years. Thus nitrilase has played a crucial role in production of commercial carboxylic acids in chemical industry and detoxification of nitrile-contaminated w...
