A novel redox driven chemiluminescent material built on a terthienyl system, namely 5,7-di-ethylenedioxythiophen-2-yl-2,3-dihydro-thieno[3,4-d]pyridazine-1,4-dione (ETE-Lum), which is soluble in both organic media and basic aqueous solution was synthesized and characterized. Furthermore, its polymer, PETE-Lum, which is one of the most rare examples of chemiluminescent polymeric materials bearing a pyridazine unit, was obtained successfully by electrochemical means. Both of the materials give chemiluminescence either by treatment with oxidants (H2O2 and/or KMnO4) or by the application of a potential pulse.


Synthesis of chiral acetoxy lactones via the Baeyer-Villiger oxidation of cyclic aromatic acetoxy ketones
Demir, Ayhan Sıtkı; Aybey, Asuman (Elsevier BV, 2008-12-01)
The alpha-acetoxylation of indanones and tetralones by using Mn(OAc)(3) followed by the enzyme catalyzed kinetic resolution of acetoxy ketones furnished both of the enantiomers of alpha-acetoxy ketones in good chemical and optical yields. The Baeyer-Villiger oxidation of alpha-acetoxy ketones with m-CPBA, CF(3)SO(3)H, and CH(2)O(2), at rt gives the corresponding lactones without racemization. The acetoxy ketone moiety migrates selectively in order to form lactones. The mild hydrolysis of lactones affords ph...
Synthesis, characterization, crystal and molecular structure of 1,5-Dihydro-2H-cyclopenta[1,2-b : 5,4-b ']dipyridin-2-imine
Baysal, Akin; Durap, Feyyaz; Gumgum, Bahattin; Yildirim, Leyla T.; Ulku, Dincer; Boga, Ayse Dilek; Özkar, Saim (Wiley, 2007-01-01)
The reaction of 1,5-diliydro-2H-cyclopenta[1,2-b:5,4-b'ldipyridin-2-one (3) with an alkylamine (butvlamine, hexylamine or ethylenediamine) yields, quite unexpectedly and in the absence of catalyst, the novel compound 1,5-dihydro-2H-cyclopentafl,2-b:5.4-b']dipyridin-2-imine (4) as the sole, analytically pure, solid product, which was fully characterized. The structure of 4 was unequivocally solved by single-crystal X-ray-diffraction analysis. The compound crystallizes in a monoclinic cell (space group P 2(1/...
Synthesis of various camphor-based chiral pyridine derivatives
Tanyeli, Cihangir; Isik, M (Elsevier BV, 2004-07-19)
(+)-beta-Hydroxymethylenecamphor 1 and enamines 2a-e were transformed into chiral camphor-based pyridine derivatives 3a-e via a tandem condensation reaction in good yields.
A novel synthesis of 1,2,4-oxadiazoles and isoxazoles
KIVRAK, Arif; Zora, Metin (Elsevier BV, 2014-01-28)
A novel synthesis of 1,2,4-oxadiazoles and isoxazoles is described by utilizing the reactions between amidoximes and alpha,beta-alkynic aldehydes and/or ketones. Conjugate addition products, obtained from amidoximes and alpha,beta-alkynic aldehydes and/or ketones, afford 1,2,4-oxadiazoles and isoxazoles when treated with bases and acids, respectively. 1,2,4-Oxadiazoles can also be synthesized directly from amidoximes and alpha,beta-alkynic aldehydes in a one-pot manner under basic conditions. The reactions ...
Synthesis of thio- and furan-fused heterocycles: furopyranone, furopyrrolone, and thienopyrrolone derivatives
ERGUN, Merve; Dengiz, Çağatay; OZER, Merve Sinem; ŞAHİN, Ertan; BALCI, METİN (Elsevier BV, 2014-09-02)
We report herein the synthesis of a novel class of compounds, ethyl 4-oxo-4H-furo[3,2-c]pyran-6-yl carbonate, (7E)-7-[(dimethylamino)methylene]-4H-furo[3,2-c]pyran-4,6(7H)-dione, 5-oxo-N-phenyl-2,5-dihydro-4H-furo[3,2-b]pyrrole-4-carboxamide,and 5-oxo-N-phenyl-5,6-dihydro-4H-thieno[3,2-b] pyrrole-4-carboxamide starting from the corresponding acid derivatives. Intramolecular cyclization in the presence of thionyl chloride formed the target fused ring systems. Additional transformation was seen in the cycliza...
