Synthesis of alkyl 2-(4-oxoquinazolin-3(4H)-yl) acrylate by nucleophilic additionof alkyl propiolates catalysed by Ph3P
4-Hydroxyquinazoline undergoes neutral conditions with alkyl propiolates in the presence of triphenylphosphine (0.26g), and by α substituation the corresponding 2-(4-oxoquinazolin-3(4H)-yl acrylate was obtained in good yields.
متن کاملIsoquinoline Promoted Synthesis of alkyl 2-(1-alkyl-5-oxo-3-phenyl-2-thioxotetrahydro-4H-imidazol-4-yliden) acetate derivatives
Derivatives of thiazolidinone ring systems are known to act as anti-HIV infections , analgesic, anti-bacterial, anti-convulsant, anti parasitic, potential anti-inflammatory and herbicidal agents. Due biological activities of thiazolidinones ring, several methods for their synthesis have been illustrated in literature. Imidazolidine-2-thiones were synthesized by the oxidative cyclization of 1-be...

متن کاملRegioselective synthesis of 1-(2,6-dichloro-4-trifluoromethylphenyl)- 4-alkyl-1H-[1,2,3]-triazoles.
A new and efficient method for the synthesis of 1-(2,6-dichloro-4-trifluoromethylphenyl)-4-alkyl-1H-[1,2,3]-triazoles by the room temperature 1,3-dipolar cycloaddition of (2-azido-1,3-dichloro-5-trifluoromethyl)benzene with terminal alkynes in the presence of Cu (I) salt as catalyst is reported. All the reactions gave 1,4-disubstituted products with high regioselectivity, as no 1,5-disubstitute...
متن کاملSynthesis of alkyl-branched fatty acids
Alkyl-branched fatty compounds are of interest for industrial products in the cosmetics and lubricant areas. In this review, clayand zeolite-catalyzed isomerizations of unsaturated fatty compounds, especially of oleic acid, are discussed. While clay-catalyzed reactions give most complex mixtures of dimeric fatty acids and of monomeric so-called “isostearic acid”, the zeolite-catalyzed process y...
