Article Citation - WoS: 2Citation - Scopus: 2Palladium-Catalysed Regio- and Stereoselective Arylative Substitution of Gamma,delta-Epoxy Esters and Amides by Sodium Tetraaryl Borates(Royal Society of Chemistry, 2020) Bilgi, Yasemin; Kuş, Melih; Artok, LeventPalladium-catalysed reactions of gamma,delta-epoxy-alpha,beta-unsaturated esters and amides with NaBAr(4)reagents proceeded regio- and stereoselectively, producing allylic homoallyl alcohols with aryl-substituents in the allylic position for a wide range of substrates. AsPh(3)was found to be a competent ligand for the arylation reaction, whereas phosphine ligand/Lewis acidic organoboron combinations favoured the substitution reaction by oxygen nucleophiles (e.g.H2O, ROH).Article Citation - WoS: 5Citation - Scopus: 5A Rare ?-Pyranopyrazole Skeleton: Design, One-Pot Synthesis and Computational Study(Royal Society of Chemistry, 2016) Üçüncü, Muhammed; Cantürk, Ceren; Karakuş, Erman; Zeybek, Hüseyin; Bozkaya, Uğur; Soydaş, Emine; Şahin, Ertan; Emrullahoğlu, MustafaDrawing upon a consecutive amide coupling and intramolecular cyclisation pathway, a one-pot, straightforward synthetic route has been developed for a range of pyrazole fused γ-pyrone derivatives. The reaction mechanism proposed for the chemoselective formation of γ-pyranopyrazole is furthermore fully supported by experimental and computational studies. © The Royal Society of Chemistry 2016.Article Citation - WoS: 15Citation - Scopus: 14Rhodium Catalysed Chemo- and Stereoselective Arylative and Alkenylative Cyclisation Reactions of Unsymmetric Diynes Containing a Terminal Alkyne Moiety With Organoboronic Acids(Royal Society of Chemistry, 2010) Artok, Levent; Kuş, Melih; Ürer, Bağdagül N.; Türkmen, Gülşah; Aksın Artok, ÖzgeUnsymmetric diynes possessing a terminal alkyne moiety reacted with organoboronic acids both chemo- and stereoselectively to afford arylated or alkenylated exocyclic dienes by catalysis from the [Rh(cod)OCH 3] 2 complex. The use of a polar protic solvent, e.g. CH 3OH is required for the success of the process under mild conditions. © 2010 The Royal Society of Chemistry.
