    Synthesis of Α,β-Unsaturated Ketones by Rhodium-Catalyzed Carbonylative Arylation of Internal Alkynes With Arylboronic Acids
    (Georg Thieme Verlag, 2008) Kuş, Melih; Aksın Artok, Özge; Ziyanak, Fırat; Artok, Levent
    The Rh-catalyzed reaction of arylboronic acids with internal alkynes under a CO atmosphere in the presence of an acid additive afforded α,β-unsaturated ketones as the major products. Hydroacylation of internal alkynes, except in the case of diaryl acetylenes, proceeded in syn fashion, yielding the E-configured isomer. A mixture of E- and Z-isomers was obtained with diphenyl acetylene. Reactions were also highly regioselective for various nonsymmetric alkynes.

    Palladium-Catalysed Reactions of Conjugated Enyne Oxiranes With Organoborons: a Diastereoselective Method of the Synthesis of 2,4,5-Trienol Derivatives
    (Elsevier, 2017) Ziyanak, Fırat; Kuş, Melih; Alkan Karadeniz, Leman; Artok, Levent
    A palladium-catalysed reaction of conjugated enyne oxiranes with organoboron reagents is described. This method allows aryl-substituted vinylallenes containing a hydroxyl group on the allylic position to be synthesized, with good diastereomeric ratios, under mild conditions.

    Iron-Promoted 1,5-Substitution (sn2' Reactions of Enyne Acetates and Oxiranes With Grignard Reagents
    (Wiley, 2017) Taç, Doğan; Aytaç, İsmet Arınç; Karatavuk, Ali Osman; Kuş, Melih; Ziyanak, Fırat; Artok, Levent
    Acetate derivatives of 2-en-4-yne alcohols 1 and enyne oxiranes 4 regioselectively underwent 1,5-substitution (SN2′′) reactions with Grignard reagents in the presence of an iron compound to provide vinylallenes exclusively with the (E)-configuration. An alkali salt was needed to avoid the hydride-promoted reductive 1,5-substitution pathway for 1, whereas no such additive was needed for the effective conversion of 4 into the desired alkylated or arylated vinylallene structure.

    Synthesis of Vinylallenols Via Palladium-Caralyzed Arylation Reactions of (z)-2,4 Oxiranes With Organoborons
    (Izmir Institute of Technology, 2016) Ziyanak, Fırat; Artok, Levent
    Allenes are important functional groups especially in synthetic organic chemistry. Due to their unique reactivity and high level of chirality transfer, allenes can be used as building blocks in the synthesis of complex molecules. In recent decades transition-metal catalyzed synthesis of allenes with organometallic reagents has become attractive method. For the synthesis of functionalized allenes, addition of different nucleophiles with the help of various transition metals to propargylic compounds bearing a leaving group has been mostly used. Transition metals are crucial for these reactions for shifting them from SN2 to SN2’ for the formation of allenes. Within the context of this research, a novel palladium-catalyzed arylation reactions of (Z)-2,4-enyne oxiranes with organoborons have been investigated. As a result of the 1,5-substitution reaction, aryl-substituted vinylallenes bearing a hydroxyl group on the allylic position (7-aryl-3,5,6-trien-2-ol) were obtained in high yields and diastereoselectivities. We were able to also disclose that Diels-Alder adducts could be obtained with excellent endo and facial selectivities when the vinylallen types of this study were reacted with dienophiles.

    Rhodium-Catalysed Alkoxycarbonylative Cyclisation Reactions of 1,6-Enynes
    (Izmir Institute of Technology, 2010) Ziyanak, Fırat; Artok, Levent
    Transition metal-catalyzed carbonylation reactions of unsaturated systems that contain alkynyl moiety became usually used methodology for the synthesis of biologically active .,. unsaturated carbonyl compounds (Mise et. al., 1983, Yoneda et. al., 1999, Artok et. al., 2009). One type of these reactions is the alkoxycarbonylation reaction of unsaturated systems for the C-C bond formation with transition metals in the presence of alcohol and CO (Scrivanti et. al., 1998). In literature beside alkynes enyne molecules that contain more than one unsaturated moiety could also undergo transition metal-catalyzed carbonylation reactions (Rivero et. al., 2003, Shibata, 2006). Pauson-Khand reactions are well known and used reactions in literature for enyne molecules These type of reactions are transition metal-catalyzed carbonylative cyclization reactions of enyne molecules. However in literature there is no such an example for the alkoxycarbonylative reactions of 1,6-enynes. In this study rhodium-catalyzed alkoxycarbonylative cyclization reactions of 1,6 enyne molecules in the presence of alcohol and CO was performed.

    Rhodium-Catalysed Alkoxycarbonylative Cyclisation Reactions of 1,6-Enynes
    (John Wiley and Sons Inc., 2011) Ziyanak, Fırat; Kuş, Melih; Artok, Levent
    The rhodium-catalysed carbonylation of 1,6-enynes possessing an electron-deficient alkenyl moiety in an alcohol reagent in the presence of a rhodium complex proceeded stereo- and chemoselectively to afford exocyclic α,β-enoates.
