Intramolecular Gold-Catalyzed and NaH-Supported Cyclization Reactions of N-Propargyl Indole Derivatives with Pyrazole and Pyrrole Rings: Synthesis of Pyrazolodiazepinoindole, Pyrazolopyrazinoindole, and Pyrrolopyrazinoindole
(American Chemical Society, 2015)
Gold-catalyzed and NaH-supported intramolecular cyclization of N-propargyl indole derivatives with pyrazole and pyrrole units attached to indole is described. An efficient route to the synthesis of pyrazolodiazepinoindole, ...
Design of pyrazolo-pyrrolo-pyrazines and pyrazolo-pyrrolo-diazepines via AuCl3-catalyzed and NaH-supported cyclization of N -propargyl pyrazoles
(American Chemical Society, 2015)
A concise synthetic methodology for new heterocyclic scaffolds, such as pyrazolo-pyrrolo-pyrazine and pyrazolo-pyrrolo-diazepine skeletons, was developed. The key features of this method include (i) synthesis of pyrrole-derived ...
Synthesis, characterization of poly-2- (2-hydroxybenzylideneamino)-6- phenyl-4,5,6, 7-tetrahydrobenzo[b]thiophene-3-carbonitrile: Investigation of antibacterial activity and optical properties
(2012)
The oxidative polycondensation reaction conditions of 2-(2- hydroxybenzylideneamino)-6-phenyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3- carbonitrile were examined. The magnitude of the reflectance of the polymer decreases ...
Lightlike hypersurfaces of a semi-riemannian product manifold and quarter-symmetric nonmetric connections
(Hindawi Publishing Corporation, 2012)
We study lightlike hypersurfaces of a semi-Riemannian product manifold. We introduce a class of lightlike hypersurfaces called screen semi-invariant lightlike hypersurfaces and radical anti-invariant lightlike hypersurfaces. ...
Hititçe metinlerde geçen KUR Hulana-/ KUR SIG 'Yün Nehri ülkesi' üzerine yeni bir değerlendirme
(Türk Tarih Kurumu Başkanlığı, 2016)
Hititçe metinlerde nadiren adına rastladığımız ama aslında stratejik olarak anahtar bir rol oynayan “KUR IDHulana-”: Hulana Nehri Memleketi’nin lokalizasyonuna yönelik birkaç teklif bulunmaktadır. Bir taraftan Hitit ...
