Summary, etc. <p>In recent years, the thioisatin (benzo[b]thiophene-2,3-diones) have attracted considerable attention due to their ability to act as intermediates in the preparation of a series of fused spiroheterocycles. The benzothiophenic frameworks are important targets in synthetic and medicinal chemistry because this fragment is a key moiety in a wide number of natural and synthetic agents. Subsequently the present study deals with the synthesis of a variety of spiroheterocycles for which different strategies have been evolved <em>viz.</em> [4+2] photocycloaddition (spiropyrans), cyclocondensation (benzodiazocine), nucleophilic cyclization (spirothioazolidinones) and air oxidation (disulfides). semicarbazide reacts with thioisatin at 3‑position (thiosemicarbazones, 2-hydroxy-(2<em>H</em>)-3,3-diaryl- and 3-hydroxy-3<em>H</em>-2,2-diaryl-benzo[b]thiophenes hydroxyl compounds), 4,9-dimethylthiophanthrenes.</p><p> </p>
