C2-Symmetric chiral diamine ligands for enantiomeric recognition of amino acid esters and mandelic acid by proton nmr titration method
Aral, Hayriye; Aral, Tarık; Çolak, Mehmet; Ziyadanoğulları, Berrin; Ziyadanoğulları, Recep (TÜBİTAK, 2013-07-08)Two novel C2 -symmetric chiral diamines containing α-phenylethyl and α-(1-naphthyl)ethyl chiral subunits were prepared with quantitative yields. Enantiomeric recognition properties of these simple structured diamine ligands ... -
Development of a novel amide silica stationary phase for the reversed phase HPLC separation of different classes of phytohormones
Aral, Tarık; Aral, Hayriye; Ziyadanoğulları, Berrin; Ziyadanoğulları, Recep (Journals & Books, 2013-05-14)A novel amide-bonded silica stationary phase was prepared starting fromN-Boc-phenylalanine, cyclo-hexylamine and spherical silica gel (4mm, 60 Å). The amide ligand was synthesised with high yield. Theresulting amide bonded ... -

Aral, Hayriye; Aral, Tarık; Ziyadanoğulları, Berrin; Ziyadanoğulları, Recep (Elsevier, 2013-11)A novel amide-bonded silica stationary phase was prepared starting from N-Boc-phenylalanine, cyclohexylamine and spherical silica gel (4 μm, 60 Å). The amide ligand was synthesised with high yield. The resulting amide ... -
HPLC separation of different groups of small polar compounds on a novel amide-embedded stationary phase
Aral, Hayriye; Aral, Tarık; Çelik, Kadir Serdar; Ziyadanoğulları, Berrin; Ziyadanoğulları, Recep (Elsevier, 2014-05-10)Retention behaviors of an amide-embedded silica base stationary phase, which was recently developed by our group, were studied by using six different groups of small polar compounds including phenolic compounds, substituted ... -
Synthesis of a mixed-model stationary phase derived from glutamine for HPLC separation of structurally different biologically active compounds: HILIC and reversed-phase applications
Aral, Tarık; Aral, Hayriye; Ziyadanoğulları, Berrin; Ziyadanoğulları, Recep (Elsevier, 2015-01)A novel mixed-mode stationary phase was synthesised starting from N-Boc-glutamine, aniline and spherical silica gel (4 μm, 60 Å). The prepared stationary phase was characterized by IR and elemental analysis. The new ... -
