Perhydro-3,l-benzothiazine-2-thiones

A novel construction of 2-imino-1,3-benzothiazin-4(3//)-ones (208) utilizes the cyclocondensation of thioureas and 2-iodobenzamides (209) in the presence of a nickel catalyst (Equation (26)) <90CL2205>, and dithiocarbamic acid reacts with 2-benzylidenecyclohexanone to form stereoisomeric perhydro-3,l-benzothiazine-2-thiones (210) (Equation (27)) <87TL571>.
