ISSN: 0941-1216Keywords: Chemistry ; Organic ChemistrySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: About the Synthesis of 6-nitro-substituted 2H-Benzo[b]thiopyran Derivatives Starting from 2-Mercapto-5-nitro-benzaldehydeBenzene derivatives useful as C3S-building blocks for the synthesis of 2H-benzo[b]thiopyrans are not easily available. The synthesis starting with 2-chloro-benzaldehyde via 2-chloro-5-nitrobenzalde-hyde to 2-mercapto-5-nitro-benzaldehyde-tert-butylimin 1b and its cyclisation to 2H-benzo[b]thiopyrans (2a - h) and (3a - d) is described. By reaction with acceptor substituted alkenes, e.g. acroleine or ω-nitrostyrene respectively 2-chloro-propenes, e.g. substituted ß-chloroacroleines or 2-chloro-propene-1,3-dicarboxylates the compounds 2a - h and 3a - d are obtained. Vilsmeier's reaction of the diester 3d with DMF/POCl3 yields the formyl compound 4.Additional Material: 4 Tab.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 0021-8383Keywords: Chemistry ; Organic ChemistrySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: Reactions of β-Chlorovinylaldehydes. V. The Formation of 2,2′-Thiopyrylocyanine Dyes from 2-(α-Formylalkylidene)-2H-thipyranesSubstituted β-chlorocrotonaldehydes react with Na2S · 9H2O to form 2-(α-formyl-alkylidene)-2H-thiopyranes 1. The corresponding thiopyrylium salts 2 which are easily available from 1 and strong acids exist in the enolic form (2-β-hydroxyvinyl-thiopyrylium salts). They are converted at room temperature in methanol solution to dark green compounds, which are identified as 2,2′-thiopyrylotrimethincyanine dyes 3. The mechanism of formation of compounds 3 is discussed.Additional Material: 3 Tab.Type of Medium: Electronic ResourceURL: -

The structure of the stable red products with Z-configuration (side chain in position 2 of the ring) is elucidated by means of several analytical and spectroscopic methods including X-ray analysis of compounds 1h and lk.Treating of 1 with Vilsmeier reagent yields title compounds 2 with a remarkable less reactive formyl group at the exo-methylene group. There is obviously a shielding effect of the carboxylate groups.Additional Material: 3 Ill.Type of Medium: Electronic ResourceURL:
