Synthesis of 5-amino-1-aryl-4-cyanoimidazoles from formamidines under solvent-free condition
The aryl-(Z)-N-[2-amino-1,2-dicyanovinyl]formamidine 2 cyclize in solvent-free conditions and in the presence of a base to give a 5-amino-1-aryl-4-cyanoimidazoles 3. Silica sulfuric acid as an efficient and reusable heterogeneous catalyst has been used for the preparation of amidines 2 from formimidate 1 through reaction with aromatic amines at room temperature and in good to excellent yields. ...

متن کاملSynthesis of 2-Amino-4hydroxy-1H-Pyrrole-3-Carbonitrile from Glycine Under Microwave Irradiation
Reaction of Glycin with Malononitrile afforded respective Pyrrole. Pyrrole is one of the heterocyclic compounds with very important biological activities. Heterocycles are extremely important because of their wide range of applications that goes from their use as pharmaceuticals and agrochemicals to dyestuffs and additives. In this view, it was proposed to synthesize pyrrole-3-carbonitrile deri...
متن کاملSynthesis of 2-amino-3-benzyl-5-(p-hydroxyphenyl)pyrazine.
2-Amino-3-benzyl-5-(p-hydroxyphenyl)pyrazine (2), a precursor of Watasenia preluciferin (coelenterazine) (1), is widely distributed in marine bioluminescent animals. It was prepared from p-hydroxyphenylglyoxal aldoxime (5) in two steps; by condensation with or-aminophenylpropiononitrile in the presence of TiCl4 in pyridine, followed by reduction of the resulting N-oxide (6) with Zn-AcOH in CH2C...
