Özbey, S; Kaynak, FB; Togrul, M; Demirel, N; Hosgören, H (R Oldenbourg Verlag, 2003)A new type of inclusion complex, S(-)-1 phenyl ethyl ammonium percholorate complex of R-(-)-2-ethyl-N-benzyl-4,7,10,13-tetraoxa-1-azacyclopentadecane, has been prepared and studied by NMR, IR and single crystal X-ray ... -
Crystal structure of N,N?-bis(dodecyl)diaza-18-crown-6 complexed sodium perchlorate
Ozbey, S; Kendi, E; Hosgoren, H; Togrul, M (Springer, 1998)The crystal structure of a new complex of a diaza-crown ether having two side arms has been determined from X-ray diffraction data. The compound crystallizes in space group P (1) over bar with cell dimensions a = 9.982(1), ... -
The enantiomeric recognition of chiral organic ammonium salts by chiral monoaza-15-crown-5 ether derivatives
Turgut, Y; Sahin, E; Togrul, M; Hosgören, H (Pergamon-Elsevier Science Ltd, 2004)Novel chiral monoaza-15-crown-5 ether derivatives 1 and 2 were prepared frorn L-phenylalaninol and L-leucinol, respectively. The effect of the substituent at the stereogenic center on chiral recognition and enantioselectivity ... -
Photomodulated molecular recognition of the guanidinium cation
Hunter, CA; Togrul, M; Tomas, S (Royal Soc Chemistry, 2004)Azobenzene moieties were incorporated into a synthetic receptor allowing its affinity for the guanidinium cation to be modulated ten-fold by photoirradiation and/or heating. -
Saligenin derivative borocryptands
Togrul, M; Sünkür, M; Kaynak, FB; Hosgören, H; Özbey, S (Science Reviews Ltd, 2003)A new lithium receptor based on the combination of the [11] macrocyclic core and two 4-tert-butyl saligenin units was designed and prepared. -
Solvent extraction of boron with 1,2-dihydroxy-4-oxadodecane (DHD) in n-amyl alcohol
Hosgoren, H; Tural, S; Kahraman, F; Togrul, M; Karakaplan, M (Marcel Dekker Inc, 1997)In the work presented here, 1,2-dihidroxy-4-oxadodecane (DHD) was synthesized and used for the solvent extraction of boron. DHD was prepared from glycidol and octanol by thermal epoxide ring opening reaction without using ... -
Synthesis of chiral crown ethers and complexation with chiral protonated amine compounds
Togrul, M; Demirel, N; Kaynak, FB; Özbey, S; Hosgören, H (Springer, 2004)The X-ray crystal structure of IX, perchlorate salt of R-(-)-2-ethyl-N-benzyl-4,7,19,13-tetraoxa-8,9-benzo-1-azacyclopentadec-8-ene has been determined. In the molecule, the protonated nitrogen atom participates in two ... -
Synthesis of chiral monoaza-15-crown-5 ethers from a chiral amino alcohol and enantiomeric recognition of potassium and sodium salts of amino acids
Togrul, M; Askin, M; Hosgoren, H (Pergamon-Elsevier Science Ltd, 2005)The enantiomeric recognition of chiral monoaza-crown ethers for amino acids as their sodium and potassium salts has been investigated by UV-vis. The highest discrimination was observed for TrpK (D/L = 6.47). The reversed ... -
