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. ...

Lanthanide(III) chloro complexes of 4[N-(4’-hydroxy-3’-methoxybenzalidene) amino] antipyrine semicarbazone (HMBAAPS) (I) and 4[N-(3’,4’,5’-trimethoxybenzalidene) amino] antipyrine semicarbazone (TMBAAPS) (II) with the general composition LnCl3.2L (Ln = La, Pr, Nd, Sm, Gd, Tb, Dy or Ho; L = HMBAAPS or TMBAAPS) are reported. All the complexes were synthesized in ethanolic medium and refluxed the ...
متن کاملThe Incorporation of Radiocarbon from 4-amino-5- Imidazolecarboxamide into the Purines of Tumor-bearing
The compound 4-amino-5-imidazolecarboxamide first was isolated by Stetten and Fox (1) from the medium of Escherichia coli which had been inhibited by sulfonamides. It was identified by Shive et al. (2) and recognized as a possible precursor of nucleic acid purines. Schulman et al. (3) showed that pigeon liver homogenates can convert 4-amino-5-imidazolecarboxamide to hypoxanthine, whereas the in...
