Ueber Verbindungen des Thiazols (Pyridins der Thiophenreihe)

Abstract

NH Endlich sei noch ein Vorschlag zur Benennung einer besondera auagezeichneten Reihs von Substitutiousproducten, aller derartigen Substanzen gemacht. Ein Ueberblick iiber dieso Derivate zeigt einmal, dam dieselben ganz vorwiegend das zwiachen den beiden fremdartigen Atomen eingeschlossene Kohlenstoffatom betreffen, also der Formel /CX entsprechen. Man gedenke der homologen Condensationsproducte , welche aus o-Amidophenolen , Thioamidopbenolen, Diaminen und den Homologen der AmeisensEure gebildet werden, ferner des 30xy-und Amido-Carbamidophenolsa (sogen. Phenylen-NA-(S,NH,O) 1) Diem Berichte XX, 2262; vergl. auch P. Jacobson, dieseBerichte XX, 9 Diem Berichte XIX, 1302. 1895 n. a. 0. ') nicse Berichte SIII, S untl 1 2 3. 2, Diehe Berichte XVI, 34.5.

Utility of thiocarbamoyl moiety in synthesis of some new sulphur containing heterocyclic compounds and evaluation of their antimicrobial activity

“…In this work, we describe generally applicable extension of this synthetic approach, first was reported by Hantzsch and Weber [23]. Thus, the base catalyzed reaction of the acidic methylene compound 1 with phenyl isothiocyanate in dry N,Ndimethylformamide at room temperature in basic medium led to the formation of the non-isolable intermediate 2 which gave thiocarbamoylderivative3upon treatment with dilute HCl (Scheme 1).…”

Facile Synthesis of Thiazole, Thiazine and Isoindole Derivatives via EDA Approach and Conventional Methods

“…The IR spectra were recorded on a Jasco FTIR-450 Plus IR spectrophotometer. The NMR spectra were obtained on a JHA-LAA 400 WB-FT spectrometer (300 MHz for 1 H NMR, 75 MHz for 13 C NMR) with [D 6 ]DMSO as a solvent. Chemical shifts are quoted in δ and are referenced to TMS.…”

Synthesis of bicyclo[3.3.1]nonane derivatives containing fused heterocyclic rings

“…Compounds 4 and 8 were synthesized in two steps by Hantzsh 14 . The first step of condensation was performed in ethanol by reflux for 3 hours.…”
