Cyclization reactions of N-(2,2-dialkoxyethyl)-1,4-benzothiazine lactams 2 and 1,4-benzothiazine-sulfones 10 lead to the corresponding pyrrolo[1,2,3-de]-1,4-benzothiazines 4 and 12, respectively, by using the dioxane/p-toluenesulfonic acid or polypho

Acid catalyzed cyclization reactions of both 3-alkyl- and 3-aryl-substituted N-(2,2-dialkoxyethyl)-3,4-dihydro-2H-1,4-benzothiazines (2) lead to 2,3-dihydro-pyrrolo[1,2,3-de]-1,4-benzothiazines (3). The pyrrolobenzothiazine structure was deduced on t
