experimental part, p. 597 - 603 (2011/07/07)
A series of novel 1-phenylthieno[1,2,4]triazolo[4,3-a]pyrimidin-5(4H)-one derivatives 5 and 6 were synthesized by oxidative cyclization of thienopyrimidinonyl hydrazones using iodobenzene diacetate.
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
