Jacobsen, Niels,Kolind-Andersen, Hans
, p. 911 - 914 (2007/10/02)
The reaction of bis(2-aminophenyl) disulphide 1 with methyl or ethyl aryl- or pyridylacetates and sodium hydride gives the title compounds in good yield and high purity.The reaction is general, the starting materials easily available and the workup is simple and rapid.
The Synthesis and Reactions of 4H-Tetrazolobenzothiazines
Kay, David P.,Kennewell, Peter D.,Westwood, Robert
, p. 1879 - 1884 (2007/10/02)
The synthesis of 4H-tetrazolobenzothiazines via an intramolecular dipolar addition reaction of 2-(2-azidophenylthio)acetonitrile is described.The methylene protons of the thiazine ring were found to be sufficiently acidic to be readily functio
