Sert, Yusuf; Gümüş, Mehmet; Gökçe, Halil; Kani, İbrahim; Koca, İrfan (Elsevier Science BV, 2018)The target compound 3-(3-(4-chlorobenzoyl)-1-phenyl-1H-pyrazole-5-carbonyl)-7-methoxy-2H-chromen-2-one was characterized by FT-IR, Laser-Raman, NMR chemical shift, UV-Vis. and single-crystal X-Ray diffraction spectroscopic ... -
Preparation of perinones via a novel multicomponent synthesis of isoindole scaffold
Üngören, Sevket Hakan; Koca, İrfan; Yılmaz, Filiz (Pergamon-Elsevier Science LTD, 2011)A convenient procedure for the preparation of isoindole derivatives is described. The method is based on the multicomponent reaction of heterocyclic ketene aminals with dialkyl acetylenedicarboxylates in presence of DMAP. ... -
Spectroscopic (FT-IR, Laser-Raman and NMR) and conformational analysis on novel pyrazole beta-keto ester compound
Gümüş, Mehmet; Sert, Yusuf; Özdemir, Şahin; Gökçe, Halil; Kani, İbrahim; Koca, İrfan (Elsevier Science BV, 2018)Our goal in this study is to submit a comprehensive theoretical study of novel compound. Therefore, we perused and analyzed the experimental (real form) and theoretical (gas form) vibrational frequencies for the most stable ... -
Spectroscopic investigation of 2-(4-benzoyl-1,5-diphenyl-1H- pyrazol-3-yl)-4H-naphto[2,3-d][1,3] oxazin-4-one molecule
Sert, Yusuf; Gümüş, Mehmet; Kamaci, Volkan; Gökçe, Halil; Kani, İbrahim; Koca, İrfan (World Scientific Publ Co Pte LTD, 2017)In this present study, the experimental and theoretical vibrational frequencies of an important pharmacological molecule 2-(4-benzoyl-1,5-diphenyl-1H-pyrazol-3-yl)-4H-naphto[2,3-d][1,3] oxazin-4-one have been researched. ... -
Synthesis and Structural Characterization of Pyrrole Heterocyclic Systems Bearing Amino Acid Units: Novel Pyrrol-3-ones, Pyrrolo[1,2-a][3,1]benzoxazines, and Pyrrolo[2,1-b][1,3]oxazoles
Koca, İrfan; Sacmaci, Mustafa; Yılmaz, Filiz; Üngören, Sevket Hakan (Wiley-Blackwell, 2014)Furan-3-one derivatives 1 were converted into 2-hydroxy-pyrrole-3-ones 4 by reacting with various - and -amino acids. In contrast, the reaction of furan-3-ones and 1-aminocyclobutanecarboxylic acid afforded spiro-pyrrolo ... -
The synthesis of new pyrrolo[1,2-a]perimidin-10-one dyes via two convenient routes and its characterizations
Koca, İrfan; Üngören, Sevket Hakan; Kibriz, İbrahim E.; Yılmaz, Filiz (Elsevier Sci LTD, 2012)Efficient synthesis of pyrrolo[1,2-a]perimidin-10-ones (4, 8) are accomplished via two new convenient methods in moderate yields. The first method is the reaction of oxalyl chloride with heterocyclic ketene aminals (HKAs) ... -
Synthesis, spectroscopic and theoretical studies of ethyl (2E)-3-amino-2-({[(4-benzoyl-1,5-diphenyl-1H-pyrazol-3-yl)carbonyl]amino}carbonothioyl)but-2-enoate butanol solvate
Koca, İrfan; Sert, Yusuf; Gümüş, Mehmet; Kani, İbrahim; Cirak, Çağrı (Pergamon-Elsevier Science LTD, 2014)We have synthesized ethyl (2E)-3-amino-2-({[(4-benzoyl-1,5-diphenyl-1H-pyrazol-3-yl)carbonyl]amino}carbonothioyl)but-2-enoate (2) by the reaction of 4-benzoyl-1,5-diphenyl-1H-pyrazole-3-carbonyl chloride (1), ammonium ...
