2,1-Benzisothiazoles. XIII . Intermediates and Products in the Sulfur Extrusion Reaction of 2,1-Benzisothiazolines-3(1H)-one. A New Synthesis of 11H-Pyridoquinazolin-11-one ("Pyracridone")

Triethyl phosphite abstracts sulfur from 2,1-benzisothiazolin-3(1H)-one (1); a reaction intermediate is the spirocyclic compound 11, and products include the benzoxazine 6 and polyanthraniloyl compounds.In the presence of pyridine, pyracridone (13) is formed.The ketene-imine 9 is probably not an intermediate in these reactions.The reactions of other nucleophiles with 1 and with its N-methyl derivative 15, have been examined.
