REACTIONS OF o-AMINOTHIOPHENOL WITH α,β-UNSATURATED DICARBONYL SYSTEMS. FACILE SYNTHESIS OF BENZOTHIAZINES AND BENZOTHIAZEPINES
Balasubramaniyan, V.,Balasubramaniyan, P.,Shaikh, A. S.
, p. 2731 - 2738 (1986)
When treated with maleanilic/fumaranilic acids or esters or the corresponding imides or isoimides, o-aminothiophenol furnishes benzothiazines, whereas treatment of o-aminothiophenol with acrylic acids/esters furnishes benzothiazepines.The orientational pr
Reactions of Cyclic Anhydrides: Part V - Acid-catalysed Esterification of Maleanilic and Fumaranilic Acids and Evidence of Activation by Carboxamido Function
Patel, M. V.,Balasubramaniyan, V.
, p. 804 - 805 (2007/10/02)
Maleanilic and fumaranilic acids undergo acid catalysed esterification with methanol under very mild conditions.Intramolecular activation involving carboxamido group appears likely in this reactions.
