Synthesis of ferrocenyl quinones and polyquinanes
Eralp, Tuğçe; Zora, Metin; Department of Chemistry (2005)
With the discovery of antitumor activity of ferrocene derivatives, research on new ferrocene derivatives have gained importance. For this purpose, we have investigated the synthesis of ferrocenyl quinones starting from squaric acid. Several quinone derivatives are known to have antitumor and antibiotic activities. In this research, by combining ferrocene and quinone moieties, we have targeted ferrocenyl quinones which are supposed to have enhanced potential antitumor activity. Thermolysis of ferrocenyl-subs...
Synthesis of Iodo-substituted spiro-fused pyridine derivatives
Teke, Ecem; Zora, Metin; Department of Chemistry (2014)
Spiro cyclic molecules have gained significance because of their biological activities and electronic properties. Spiro frameworks are present in importance natural products and optoelectronic materials. Moreover, due to steric strain, the presence of a spiro carbon atom induces easy rearrangements that can lead to different cyclic products. Although there are some methods to synthesize spiro compounds, the synthesis of iodo-substituted spiro-fused pyridines have not been studied. Accordingly, in this thesis...
Synthesis of dioxin & tetra aryl pyrazine derivatives and their applications
Okyar, Burcu; Özçubukçu, Salih; Günbaş, Emrullah Görkem; Department of Chemistry (2019)
Aggregation induced emission (AIE) luminogens have attracted great attention in various disciplines of science in last decades. The photophysical properties and structural design of this type of luminogens make it possible to have large variety of applications in fluorescence sensors, cell imaging, microstructures aggregate and electroluminescence devices etc. All these studies promote researchers to find alternative AIE luminogens and also different application areas of AIE luminogen systems. 2,3,5,6-tetra...
Synthesis of ferrocenyl quinones
Zora, Metin; Acikalin, S (Elsevier BV, 2003-03-03)
A squarate-based synthesis of ferrocenyl quinones is described. Thermolysis of ferrocenyl-substituted cyclobutenones, prepared from ferrocenyl cyclobutenediones and alkenyllithiums, affords hydroquinones, which furnish, upon oxidation, ferrocenyl quinones. Ferrocenyl cyclobutenediones have been prepared from known cyclo butenediones by nucleophilic addition of ferrocenyllithium followed by hydrolysis, Pd/Cu-cocatalyzed cross-coupling with (tri-n-butylstannyl)ferrocene or Friedel-Crafts alkylation with ferro...
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...
