It is known that pyrrole and its derivatives are a part of many important natural compounds. Polymeric semiconductors also were obtained on the basis of 2,5-dithienyl-pyrrole electropolymerization and its derivatives. The work deals with the synthesis of 2,3-dithiophenyl-1H-pyrroles by the reaction of 2,2'-thionine with various enamines.


Synthesis of new pyrrole derivatives from npropargylic β-enaminones
Kanova, Nilay; Zora, Metin; Department of Chemistry (2020)
Heterocyclic compounds are a momentous area of synthetic organic chemistry because of their existence in bioactive molecules. Pyrroles, which are one of the most important classes of heterocyclic compounds, have great importance in pharmaceutical chemistry due to their biological activities. Having these characteristics makes them drawn attention of most chemists to develop new methodologies for the synthesis of pyrroles. Recently, the cyclization of Npropargylic β-enaminones has been used for the synthesis...
Synthesis of dipyrrolo-diazepine derivatives via intramolecular alkyne cyclization
Baskin, Dilges; Cetinkaya, Yasin; Balcı, Metin (2018-07-26)
A regioselective approach was developed for the synthesis of dipyrrolo-diazepine derivatives. The synthetic route to dipyrrolo-diazepines first involves the synthesis of dipyrromethanes, followed by reaction of propargyl bromide in the presence of NaH to attach one alkyne functionality to the pyrrole nitrogen atom. Intramolecular heterocyclization with NaH in DMF between the alkyne functionality and pyrrole nitrogen atom gave the desired structures in good yields.
Synthesis of Functionalized Novel alpha-Amino-beta-alkoxyphosphonates through Regioselective Ring Opening of Aziridine-2-phosphonates
Polat-Cakir, Sidika; Beksultanova, Nurzhan; Doğan, Özdemir (Wiley, 2019-11-01)
Aziridines are highly useful compounds as building blocks for the synthesis of important organic compounds. Amino acid synthesis by aziridine ring opening reaction is a good example to the use of aziridines. Although this reaction is studied by many groups, the synthesis of amino phosphonic acids is less explored. In this study, we have carried out the ring opening reaction of aziridinyl phosphonates with a variety of alcohols including the more functional propargylic and allylic alcohols. These reactions p...
Synthesis of 2-aminopyrrole-3-carboxylates via zinc perchlorate mediated annulation of alpha-cyano-gamma-ketoesters with amines
Akca, Nazmiye Bihter; Demir, Ayhan Sıtkı; Department of Chemistry (2008)
2-Aminopyrrole-3-carboxylate derivatives are important starting materials for biologically active compounds like pyrrolotriazole, pyrrolotriazine so their synthese has great importance in the synthetic organic chemistry. There are only two methods for the synthesis of 2-aminopyrrole-3-carboxylates in the literature. Therefore, there is a great need for the design and development of a new method for the synthesis of 2-aminopyrrole-3-carboxylates. In this work, 2-aminopyrrole-3-carboxylate derivatives were sy...
Synthesis of 6-halogen-substituted 2-methylene-2,3dihydro-1,4-oxazepine derivatives
İbiş, Özge; Zora, Metin; Department of Chemistry (2017)
Heterocyclic compounds are important since they are present in life naturally or synthetically. Among heterocyclic compounds, seven-membered 1,4-oxazepines are giving more attention than ever due to their wide range of biological and medicinal activities. There are many studies about their synthesis and new ones continue to appear. In this study, synthesis of halogen-substituted 1,4-oxazepine derivatives was investigated, which may have potential for biological studies. For this purpose, α,β-alkynic ketone ...
