Authors
abstract
a green and convenient protocol is described for the preparation of 1-(alkylamino)-3-(1,3-dioxoisoindolin-2-yl)-2-methyl-1-oxopropan-2-yl benzoates via one-pot three-component reaction between 2-(2-oxopropyl)isoindoline-1,3-dione, an alkyl isocyanide and an aromatic carboxylic acid in water at room temperature. the methods used to follow the reactions are tlc and nmr, which indicated that there is no side product and the products were obtained without any purification. the structures of the products were deduced from their 1h nmr, 13c nmr and ir spectra. the present methodology offers several advantages such as a simple procedure, catalyst-free, mild reaction conditions, high yields, and the absence of any volatile and hazardous organic solvents.

In this study, zirconium dodecylphosphonate was synthesized by the reported method in scientific literature. 2-Alkylbenzoxazoles were prepared from aliphatic carboxylic acids and 2-aminophenol in the presence of this catalyst under solvent-free conditions at 100°C. Their structures were recognized by IR, 1H NMR, and 13C NMR. Then, we used aromatic carboxylic acids in t...

For the first time lactic acid was applied as an efficient and green catalyst for the one-pot three-component synthesis of amidoalkyl naphthols via the condensation between arylaldehydes, 2-naphthol and amides or urea under thermal solvent-free conditions in good to excellent yields. We have demonestrated a mild and efficient eco-friendly tandem synthesis of amidoalkyl naphthols using lactic ac...
