2-(2,2-Dimethoxyethyl)-3-oxo-1,2,3,4,5,6-hexahydro-1,5-methano-7H- azocino[4,3-b]indole
Hoekelek, Tuncer; Sahin, Ertan; Uludag, Nesimi; Erdogan, Uemit Isik (INT UNION CRYSTALLOGRAPHY, 2007)The title compound, C18H22N2O3, consists of a tetracyclic ring system containing an azocino skeleton with a dimethoxyethyl group as a substituent. The benzene and five-membered rings are nearly coplanar, with a dihedral ... -
3a,4,10,10b-tetrahydro-2H-furo[2,3-a]carbazol-5(3H)-one
Caylak, Nagihan; Hoekelek, Tuncer; Uludag, Nesimi; Patir, Sueleyman (INT UNION CRYSTALLOGRAPHY, 2007)The asymmetric unit of the title compound, C14H13NO2, contains two independent molecules. In the indole ring system, the benzene and pyrrole rings are nearly coplanar, the dihedral angles being 0.48 (17) and 1.26 (17)degrees. ... -
Concise total synthesis of (+/-)-aspidospermidine and computational study: FT-IR, NMR, NBO, NLO, FMO, MEP diagrams
Serdaroglu, Goncagul; Uludag, Nesimi (ELSEVIER SCIENCE BV, 2018)Aspidospermidine is a member of the compound class known as aspidospermaten-type alkaloids. Aspidospermidine is among the most highly sought aspidosperma alkaloid targets because it comprises the basic skeletal features ... -
A DFT Investigation on the Structure, Spectroscopy (FT-IR and NMR), Donor-Acceptor Interactions and Non-Linear Optic Properties of (+/-)-1,2-Dehydroaspidospermidine
Uludag, Nesimi; Serdaroglu, Goncagul (WILEY-V C H VERLAG GMBH, 2019)In this study, (+/-)-1,2-Dehydroaspidospermidine was analyzed by elemental analysis, H-1 and C-13 NMR, and FT-IR spectra. Also, because the starting geometry is essential to evaluate the structural, electronic, and spectral ... -
Ethyl 2-(9-methylsulfonyl-1-oxo-2,3,4,9-tetrahydro-1H-carbazol-2-yl)acetate
Ozbey, Suheyla; Karayel, Arzu; Yilmaz, Ayhan; Uludag, Nesimi (BLACKWELL PUBLISHING, 2007)The title compound, C17H19NO5S, crystallizes with two molecules per asymmetric unit; these do not exhibit the same pattern of hydrogen bonds. The indole part of the carbazole skeleton is almost planar, while the cyclohexenone ... -
The evaluation of the attitudes of science teacher candidates towards chemistry lesson
Hancer, Ahmet Hakan; Uludag, Nesimi; Yilmaz, Ayhan (HACETTEPE UNIV, 2007)The aim of this study is to determine the science teacher candidates' attitude towards chemistry, which is among the field lessons, and to search whether there is a relation between the attitude and the academic success. ... -
An improved synthesis, spectroscopic (FT-IR, NMR) study and DFT computational analysis (IR, NMR, UV-Vis, MEP diagrams, NBO, NLO, FMO) of the 1,5-methanoazocino[4,3-b]indole core structure
Uludag, Nesimi; Serdaroglu, Goncagul (ELSEVIER SCIENCE BV, 2018)This study examines the synthesis of azocino[4,3-b]indole structure, which constitutes the tetracyclic framework of uleine, dasycarpidoneand tubifolidineas well as ABDE substructure of the strychnosalkaloid family. It has ... -
A novel synthesis of octahydropyrido[3,2-c]carbazole framework of aspidospermidine alkaloids and a combined computational, FT-IR, NMR, NBO, NLO, FMO, MEP study of the cis-4a-Ethyl-1(2hydroxyethyl)-2,3,4,4a,5,6,7,11c-octahydro-1H-pyrido[3,2-c] carbazole
Uludag, Nesimi; Serdaroglu, Goncagul; Yinanc, Abdullah (ELSEVIER SCIENCE BV, 2018)In this study, we performed a novel synthesis of the octahydropyrido[3,2-c]carbazole derivative 6 from 1 in five steps with a 34% overall yield. We also developed a unique compound 2 by a cyclization reaction from the ... -
Studies on the synthesis of the azocino[4,3-b]indole framework and related compounds
Uludag, Nesimi; Patir, Suleyman (HETERO CORPORATION, 2007)An efficient method for the synthesis of C-4 position alkylated azocino[4,3-b]indole 13 and 18 is described. Reduction of compounds 5, 6, 7 and 8 yielded the corresponding alcohols. Compounds 5, 6, 7 and 8 were synthesized ...
