Pyrrolo[2,3-b][1,4]benzothiazine. A new ring system from azidopyrroles

Article abstract of DOI:10.3987/com-99-8604

Nucleophilic substitutions in pyrrole series by uncharged nucleophiles, represented a valuable and versatile method to synthesize different types of key intermediates such as compounds (6), that were used to prepare the corresponding azides (10) which by thermal decomposition afforded the title ring system (11).
