One-Pot Synthesis Of Quinazolin-4(3$H$)-Ones And 2,3-Dihydroquinazolin-4(1$H$)-Ones Utilizing $N$-(2-Aminobenzoyl)Benzotriazoles, İlbi̇lge Merve Şenol, İlhami̇ Çeli̇k, İlker Avan

Turkish Journal of Chemistry

A convenient and efficient method has emerged for the one-pot synthesis of substituted quinazolin-4(3$H)$-ones and nonaromatic alkaloids. 2-Substituted quinazolin-4(3H)-ones, 2,3-disubstituted quinazolin-4(3$H)$-ones, and 2,3-dihydroquinazolin-4(1$H)$-ones were obtained at yields of 46% to 95% by a one-pot reaction of $N$-(2-aminobenzoyl) benzotriazoles with amines and orthoesters or aldehydes under catalyst-free conditions.


Design, Synthesis, And Evaluation Of The Antimycobacterial Activity Of 3-Mercapto-1,2,4-Triazole--Pyrrole Hybrids, Gheorghe Roman, Andra-Cristina Bostanaru, Valentin Nastasa, Mihai Mares Jan 2019

Design, Synthesis, And Evaluation Of The Antimycobacterial Activity Of 3-Mercapto-1,2,4-Triazole--Pyrrole Hybrids, Gheorghe Roman, Andra-Cristina Bostanaru, Valentin Nastasa, Mihai Mares

Turkish Journal of Chemistry

A series of 3-mercapto-1,2,4-triazole--pyrrole hybrids was designed as antimycobacterial agents by employing 5-(4-(1$H$-pyrrol-1-yl)phenyl)-4$H$-1,2,4-triazole-3-thiol as the scaffold onto which several types of moieties were introduced in the triazole ring at N-4 and N-2 and as substituents of the mercapto function. The aforementioned moieties are an allyl or a phenyl moiety at N-4; an aminomethyl group at N-2; or methyl, substituted benzyl, ethoxycarbonylmethyl, or substituted phenacyl at sulfur. Investigation of the compounds in the resulting library as growth inhibitors of Mycobacterium smegmatis showed that their minimum inhibitory concentration was higher than 64 mg/L.

Turkish Journal of Chemistry

The complexes of peripherally tetra-substituted metal-free (8), lead(II) 9), and zinc(II) (10) phthalocyanine derivatives were synthesized for the first time in this work. The structures of these new complex compounds have been elucidated using many spectral methods such as electronic absorption, FT-IR, $^{1}$H NMR, $^{13}$C NMR, elemental analysis, and mass spectra. The thermogravimetric behavior of compounds 8-10 was determined by thermogravimetric analysis method in addition to these spectral methods.


An Efficient Protocol For The Synthesis Of Brominated Norbornene, Norbornadiene, And Benzonorbornadiene, Selçuk Eşsi̇z Jan 2019

An Efficient Protocol For The Synthesis Of Brominated Norbornene, Norbornadiene, And Benzonorbornadiene, Selçuk Eşsi̇z

Turkish Journal of Chemistry

An efficient protocol for the synthesis of 2-bromonorbornene, 2-bromonorbornadiene, 2-bromoben- zonorbornadiene, 2,3-dibromonorbornene, 2,3-dibromonorbornadiene, and 2,3-dibromobenzonorbornadiene in good yields has been developed. 1,2-Dibromotetrachloroethane is used as the brominating agent for these reactions. The results are discussed in comparison with alternative methods in the literature.
