The reaction mechanism of the title reaction was proposed on the basis of the kinetic study.The reaction takes place in two stages considerably differing in rates.In the first, faster stage, the anion of initial substance cyclizes to 1-methyl-3-benzoyl-2-
Novel heterocycles derived from substituted aroylthioureas: Synthesis of 3,1-benzothiazin-4-ones, thieno[3,2-d][1,3]thiazin-4-ones and 1,2,4-thiadiazolo[2,3-a][3,1]benzothiazin-5-ones

A series of heterocyclic aroylthioureas has been prepared and investigated as starting materials for ring closure reactions. The formation of several new 3,1-benzothiazin-4-ones and thieno[3,2-d][1,3]thiazin-4-ones (via cyclocondensation reactions) is rep
