Abstract: The synthesis of 4-aryl-2-(3-(2-(trifluoromethyl)phenyl)-1,8-naphthyridin-2-yl)phthalazin-1(2H)-ones was performed by cyclization of 2-hydrazinyl-3-(2-(trifluoromethyl)phenyl)-1,8-naphthyridine with 2-aroylbenzoic acids in ethanol containing a catalytic amount of concentrated sulfuric acid under solid state conditions. All these synthesized compounds (8a–h) were screened for…

Abstract: Ethyl α-nitro-β-trifluoromethyl acrylate was synthesized by nucleophile-catalyzed reaction of ethyl nitroacetate with excess trifluoroacetaldehyde methyl hemiacetal and subsequent dehydration of the intermediate alcohol with P2O5. The synthesized nitro olefin regioselectively reacts with the substituted indoles…
