The synthesis of various heterocyclic compounds using acetoacetanilide[AAA], we have demonstrated that acetoactanilide are versatile intermediate for the synthesis of pyrazolopyrimidine derivatives. Thus, to explore further, we sought that the reaction of various acetoactanilide, an appropriate aldehyde and 5-amino-N-cyclohexyl-3-(methylthio)-1H-pyrazole-4-carboxamide in the presence of base in isopropyl alcohol could be an effective strategy to furnish the novel pyrazolopyrimidine derivatives. Here we describe the novel synthetic methodology for the fused pyrazolopyrimidines.

Two different series of novel β-ketoamide curcumin analogs enriched in biological activities have been synthesized. The synthesized compounds were screened for their in?vitro anti-diabetic and AGEs inhibitory activities and exhibited potent to good anti-diabetic and AGEs inhibitory activities. The molecular docking study was also performed with the α-amylase enzyme.

A new derivatization method for the detection of aliphatic and aromatic amines, based on electro-chemiluminescence (ECL) with Ru(bpy)32+ is proposed. Sample amines were derivatized to acetoacetylamide-type derivatives using diketene. The derivatives were detected by reversed-phase HPLC with ECL detection using Ru(bpy)32+.

Abstract: A series of N-substituted-6-methyl-4-{4-[5-(4-nitrophenyl)-1,3,4-oxadiazol-2-yl]methoxyphenyl}-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxamides have been synthesized by the condensation of newly synthesized {4-[5-(4-nitrophenyl)-1,3,4-oxadiazol-2-yl]methoxy}benzaldehyde with variously substituted acetoacetanilides and urea in the presence of ethanol. The synthesized compounds have been characterized by 1H, 13C NMR, IR spectroscopy, and mass spectrometry. All synthesized compounds were evaluated for in vitro antidiabetic activity using the α-amylase inhibition assay with the 3,5-dinitrosalicylic acid (DNSA) reagent.

Direct enantioselective hydrogenation of unsaturated compounds to generate chiral three-dimensional motifs is one of the most straightforward and important approaches in synthetic chemistry. We realized the Ru(II)-NHC-catalyzed asymmetric hydrogenation of 2-quinolones under mild reaction conditions. Alkyl-, aryl- and halogen-substituted optically active dihydro-2-quinolones were obtained in high yields with moderate to excellent enantioselectivities. The reaction provides an efficient and atom-economic pathway to construct simple chiral 3,4-dihydro-2-quinolones. The desired products could be further reduced to tetrahydroquinolines and octahydroquinolones.
