Copper-Catalyzed Domino Strategy Construction of Fused Benzopyrroloazepinone through the Reaction of Allenyloximes and Arylboronic Acids Ejiyeh, Negah Esnaashari; Amiri, Kamran; Bijarkani, Fatemeh Hadizadeh; Hosseini, S. Sina; Fouladi, Vahid; Fathi, Azar; Bijanzadeh, Hamid Reza; Rominger, Frank; Tanyeli, Cihangir; Balalaie, Saeed (2026-06-01) Herein, we present a novel strategy for the efficient synthesis of fused azepinone frameworks from allene-tethered oximes and arylboronic acids through a domino effect comprising a Chan-Lam coupling, [3 + 2] cycloaddition,...
Evaluation of chemical and rheological properties of warm mix asphalt binders considering binder source, additive type, and aging Yildirim, Semiha Uhde; Tanyeli, Cihangir; Güler, Ali Murat; Öztürk, Hande Işık (2026-01-01) Warm mix asphalt (WMA) technologies have long been used without compromising the performance of asphalt concrete. However, no research has yet investigated the chemo-mechanisms of WMA-modified binders considering the effec...
Computational Identification of Potential Organocatalysts (CIPOC) Reveals a 2-aminoDMAP/Urea Catalyst Superior to Its Thiourea Analogue Alsancak-Koca, Sezen; Çamlısoy, Yeşim; Bakırcı, İrem; Işık, Murat; Çelebi-Ölçüm, Nihan; Tanyeli, Cihangir (2025-01-01) Asymmetric organocatalysis by bifunctional acid- and base-type small organic molecules has emerged as a promising way to enhance stereoselective organic transformations since the beginning of this millennium. Takemoto’s te...
Electrochromic, Capacitive, and Electrocatalytic Performance of TEMPO Anchored EDOT-SN(T)S-EDOT Electrode Nemutlu, Begüm; Eker, Emre Fatih; Önal, Ahmet Muhtar; Cansu Ergun, Emine Gul; Tanyeli, Cihangir (2025-01-01) Conjugated polymers bearing TEMPO units are successfully used as catalysts for the selective oxidation of primary alcohols. Moreover, such polymers should exhibit satisfactory capacitive properties for energy storage appli...
Enantioselective Addition of 1,3,5,7-Tetramethyl-BODIPYs to Isatins by Bifunctional Quinine-Based Squaramides Dündar, Esra; Isik, Murat; Yıldırım, Erol; Tanyeli, Cihangir (2025-01-01) This work describes the development of the first enantioselective addition reaction between 1,3,5,7-tetramethyl-BODIPYs and isatin derivatives. The reaction utilizes bifunctional quinine/squaramide organocatalysts and affo...
Asymmetric Synthesis of Trifluoromethyl Substituted Spiro[Indoline‐3,4′‐Pyrano[2,3‐c]Pyrazole] Derivatives with Organocatalysts Özcan, Bilge Deniz; Kömüşdoğan, Ezgi Bayer; Şahin, Ertan; Tanyeli, Cihangir (2024-02-01) Spirocyclic compounds have always attracted attention due to their presence as a structural core in a wide variety of natural and bioactive molecules and to exhibit pharmaceutical proper ties. An asymmetric synthesis of ...
Multicomponent synthesis of stereogenic-at-boron fluorophores (BOSPYR) from boronic acids, salicylaldehydes, and 2-formylpyrrole hydrazones Bayer, Ezgi; Batool, Sania; ŞAHİN, Ertan; Yıldırım, Erol; Işık, Murat; Tanyeli, Cihangir (2024-01-01) This work describes one-step syntheses of various stereogenic-at-boron fluorochromes (BOSPYR) via multicomponent reactions involving readily accessible boronic acids, salicylaldehydes, and 2-formylpyrrole hydrazones. The d...
Organocatalytic enantioselective synthesis of dihydronaphthofurans and dihydrobenzofurans: reaction development and insights into stereoselectivity Susam, Zeynep Dilşad; Ozcan, Bilge Deniz; Kurtkaya, Enis; Yıldırım, Erol; Tanyeli, Cihangir (2022-10-01) Squaramide/cinchona alkaloid-derived bifunctional organocatalysts are in high demand in asymmetric transformations. Bifunctional quinine-derived sterically encumbered squaramide (H-bond donor) organocatalysts were used to ...
A boron dipyrromethene chiral at boron and carbon with a bent geometry: synthesis, resolution and chiroptical properties Işık, Murat; Dündar, Esra; ŞAHİN, Ertan; Tanyeli, Cihangir (2022-06-01) © 2022 The Royal Society of Chemistry.We report a boron dipyrromethene that is chiral at boron and carbon (B*C*-BODIPY) and accessible through a two-pot, one-step synthesis—an interrupted Knoevenagel condensation. The elec...
Enantioselective synthesis of 2,3-dihydrofurans using a bifunctional quinine/squaramide organocatalyst Susam, Zeynep Dilşad; Gundogdu, Gulsum; Tanyeli, Cihangir (2021-11-01) Asymmetric organocatalytic domino type Michael-S(N)2 reactions give access to enantiomerically enriched dihydrofuran derivatives that can be used as valuable chiral building blocks. A variety of alpha-bromonitroalkenes and...
