Long wavelength emitting, extended conjugation boradiazaindacenes are novel dyes with considerable ICT character. By appending a dipicolylaminylethylamine group, the parent compound was transformed into a fluorescent dye with a strong chelating ability for Zn(II) ions. The zinc complex which has bright orange fluorescence, reversibly signals anions with very large changes in both the absorption and the emission spectra. The remarkable change in the emission intensity is explained in relation to the electron donating capacity of the substituent on the styryl functionality.

A near IR di-styryl BODIPY-based ratiometric fluorescent chemosensor for Hg(II) Atilgan, Serdar; Kutuk, Ilker; Ozdemir, Tugba (Elsevier BV, 2010-02-10) A novel BODIPY-based near-IR emitting probe as a selective and sensitive fluorophore for Hg(II) is synthesized. This versatile BODIPY fluorophore is functionalized for long wavelength emission at the 3 and 5 positions via a condensation reaction in which two dithiodioxomonoaza-based crown-containing phenyl units are conjugated to the BODIPY core as a chelating unit. This designed fluorophore, employing an ICT sensor can be used effectively to detect Hg(II) cations by way of a hypsochromic shift (similar to ...
An effective new synthesis of 2-aminopyrrole-4-carboxylates Demir, Ayhan Sıtkı; Emrullahoglu, M (Elsevier BV, 2005-10-31) Efficient syntheses of 2-aminopyrroles are presented starting from beta-dicarbonyl compounds, bromoacetonitrile, and amines. Alkylation of beta-dicarbonyl compounds with bromoacetonitrile furnished alpha-cyanomethyl-beta-dicarbonyl compounds. The condensation reaction of alpha-cyanomethyl-beta-dicarbonyl compounds with amines catalyzed by p-TsOH affords the corresponding enamines in good yields. Base catalyzed cyclization via the addition of an amine moiety to the carbon-nitrogen triple bond of nitrile furn...
Synthesis of thienopyridinones via hydrazide-alkyne cyclization Cokol, Nalan Korkmaz; Erden, Kübra; Gunay, Furkan Melih; Dengiz, Çağatay; Balci, Metin (Elsevier BV, 2020-05-08) A novel and efficient method for the synthesis of thieno[3,2-c]pyridinones have been developed. The synthetic strategy relies on the synthesis of halothiophene esters utilized as substrates for subsequent Sonogashira cross-coupling reactions. Hydrazinolysis of corresponding esters and following hydrazidealkyne ring closure transformations resulted in target thienopyridinones in good yields. It is also shown that pure hydrazine monohydrate is required to facilitate the hydrazide formations.
A novel synthesis of 1,2,4-oxadiazoles and isoxazoles KIVRAK, Arif; Zora, Metin (Elsevier BV, 2014-01-28) A novel synthesis of 1,2,4-oxadiazoles and isoxazoles is described by utilizing the reactions between amidoximes and alpha,beta-alkynic aldehydes and/or ketones. Conjugate addition products, obtained from amidoximes and alpha,beta-alkynic aldehydes and/or ketones, afford 1,2,4-oxadiazoles and isoxazoles when treated with bases and acids, respectively. 1,2,4-Oxadiazoles can also be synthesized directly from amidoximes and alpha,beta-alkynic aldehydes in a one-pot manner under basic conditions. The reactions ...
New approaches to polysubstituted pyrroles and pyrrolinones from alpha-cyanomethyl-beta-ketoesters Demir, Ayhan Sıtkı; Emrullahoglu, Mustafa; Ardahan, Gulben (Elsevier BV, 2007-01-08) In this present paper, we report the efficient, regioselective one-pot synthesis of 5-alkoxy and 5-alkylsulfanylpyrrole-3-carboxylates in high yields via the zinc perchlorate-catalyzed addition of alcohols and thiols to the nitrile carbon of alpha-cyanornethyl-beta-ketoesters followed by annulation. The addition-annulation process is undertaken in aqueous solution to give 4,5-dihydro-5-oxo-1H-pyrrole-beta-carboxylates (pyrrolinones) in good yields. These 4,5-dihydro-5-oxo-1H-pyrrole-3-carboxylates are also ...
