Abstract: 1,1,2,2,7,7,8,8-Octaethoxyocta-3,5-diyne has been observed as a minor product in several syntheses utilizing 3,3,4,4-tetraethoxybut-1-yne (TEB) as starting material. In order to access this highly functionalized diyne, we have developed a procedure that provides the title compound in excellent yield.

Abstract: Novel 5,5-dimethyl-2,2-di(pyridin-2-yl)hexahydropyrimidine was synthesized in good yield by a one-pot condensation reaction of 2,2-dimethylpropane-1,3-diamine with di(pyridin-2-yl)methanoneusing dichloromethane as solvent at room temperature. The structure of the synthesized compound was assigned on the basis of its elemental analysis, UV-visible, 1H-NMR, 13C-NMR, IR, and mass spectral data.

Abstract: The synthesis of the (2S)-[3-(anthracen-9-yl)-4,5-dihydroisoxazol-5-yl]methyl 2-[(tert-butoxycarbonyl)amino]propanoate is obtained through the 1,3-dipolar cycloaddition of the stable anthracenenitrile oxide and the N-Boc protected (S)-alanine allyl ester as dipolarophile. The structure and the fluorescence properties are described upon the relative analytical and spectroscopic data.

Abstract: The title compound, N'-[2-(7,8-dimethyl-2,4-dioxo-3,4-dihydrobenzo[g]pteridin- 10(2H)-yl)ethylidene]-4-nitrobenzohydrazide (1), was obtained by the reaction of formylmethylflavin and p-nitrobenzohydrazide. The product 1 inhibited the DNA binding of nuclear factor-κB, and was characterized by 1H-NMR, 13C-NMR, electrospray ionization mass spectrometry, elemental analysis, IR and UV.
