Activation of Pyridinium Salts for Electrophilic Acylation: a Method for Conversion of Pyridines into 3-acylpyridines
Electrophilic aromatic substitution reactions of pyridines are extraordinarily challenging. Instead of C-substitution at the pyridine ring, the electrophile typically forms an adduct with the pyridine nitrogen, which even further deactivates the already electron deficient pyridine ring toward electrophilic substitution. For example, the direct nitration of pyridine may require a reaction temper...
متن کاملsingle-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
15 صفحه اولEfficient, mild and completely regioselective synthesis of substituted pyridines.
Addition of Grignard reagents to pyridine N-oxides in THF at low temperature (-78 to -20 degrees C) and treatment with TFAA provides an efficient general procedure for synthesis of substituted pyridines. The method is compatible with a range of functional groups such as esters, halogens and nitriles.
متن کاملSynthesis of substituted pyridines and pyridazines via ring closing metathesis.
RCM can be used to make aromatic heterocycles, namely pyridines and, for the first time, pyridazines; the key step after RCM involves elimination of sulfinate to provide the aromatic system.
متن کاملThe Synthesis of 2, 6 diamino- 3, 5-dinitropyridine from Direct Nitration Reaction of 2, 6 diamino pyridine in Different Temperature Conditions by Density Functional Theory
In this article, synthesis of the explosive 2, 6 (diamino) 3, 5 dinitro pyridine (ANPY) of the direct nitration reaction of 2, 6 diamino pyridine in different conditions of temperature, with density functional theory method were studied. For this purpose, at first the material contained in the both sides of reaction were geometrically optimized, then the calculation of the the...
