Reaction of 4-methoxy-4-(1-methylethenyl)-2-cyclobutenone derivatives with 2-lithiopropene and alpha-lithiostyrene: synthesis of eight-membered ring carbocycles
Zora, Metin; Yucel, B (2000-09-02)
2-Alkyl- or phenyl-substituted 4-methoxy-4-(1-methylethenyl)-2-cyclobutenones react with 2-lithiopropene or alpha-lithiostyrene to produce 4-methoxy-2,4-cyclooctadienones in moderate yield, accompanied by varying amounts of 4-methoxy-4-(1-methylethenyl)-2-cyclohexenones. The reaction is general for 2-alkyl substituted 4-methoxy-4-(1-methylethenyl)-2-cyclobutenones.
Reaction of ferrocenylcarbene complexes of Cr, Mo and W with alkynes: Synthesis of ferrocenylcyclobutenones, ferrocenylfurans and ferrocenylketoesters
Zora, Metin (Elsevier BV, 2001-07-09)
Ferrocenylcarbene complexes of Cr, Mo and W react with alkynes to produce cyclobutenones, furans and/or ketoesters. The reaction is quite sensitive to the substituents of the alkyne, regardless of the identity of the metal. Cyclobutenones are formed only in the reactions of diphenylacetylene, a rare occurrence for metal carbene complexes. Ketoesters are secondary reaction products and result From oxidation of furan derivatives during the course of the reaction and/or silica-gel chromatography.
Synthesis of 6-halogen-substituted 2-methylene-2,3dihydro-1,4-oxazepine derivatives
İbiş, Özge; Zora, Metin; Department of Chemistry (2017)
Heterocyclic compounds are important since they are present in life naturally or synthetically. Among heterocyclic compounds, seven-membered 1,4-oxazepines are giving more attention than ever due to their wide range of biological and medicinal activities. There are many studies about their synthesis and new ones continue to appear. In this study, synthesis of halogen-substituted 1,4-oxazepine derivatives was investigated, which may have potential for biological studies. For this purpose, α,β-alkynic ketone ...
Reaction of Metal-Carbene Complexes with Cyclobutenediones: The First General C-C Bond Insertion Reaction for Fischer Carbene Complexes
Zora, Metin (American Chemical Society (ACS), 1993-01-01)
Alkylcarbene-chromium complexes react with cyclobutenediones to give 2-alkoxy-4-cyclopentene-1,3-diones in moderate yield, accompanied by varying amounts of 4-cyclopentene-1,3-dione derivatives which result from reduction of the initial product by the chromium byproduct. The reaction is general for a variety of cyclobutenedione derivatives with alkoxy, alkyl, or aryl substituents. The major products of the reaction between arylcarbene complexes and cyclobutenediones are 5-alkylidenefuranone derivatives. A m...
