The reaction of N-(2-chloroethyl)diisopropylamine 1a with S2Cl2 allows the selective one-pot preparation of the tricyclic 4-(2-chloroethyl) bisdithiolothiazines 2-4 or, by addition of phosphorus pentasulfide at a late stage in the reaction, of the dithiolothiazine 5. The chloroethyl derivative 2 is also obtained from (2-diisopropylamino)ethanethiol 1b,

1,2-Thiazines and benzo derivatives
1991Sulfur atoms can exhibit a valency of four allows the formation of 1-substituted 1, 2-thiazines with a double bond between two heteroatoms, and the second bond elsewhere in the ring. Although these compounds could be described as “dihydro derivatives,” they are isomeric with 1, 2-thiazines, in which the valency of the sulfur atom is two and there is no

[Pyrazolo[3,4d][1,3]thiazine systems].
Il Farmaco; edizione scientifica, 1979The synthesis of 1,2,4,6-tetrahydro-2-methyl-3-hydroxypyrazolo [3,4-d] [1,3]thiazine-4,6-dithione is described. By spectroscopic methods the anphionic structure of this and other related compounds is demonstrated. In addition, the action of alkylating reagents upon pyrazolo-[3,4-d] [1,3]thiazine-4,6-dithionic compounds is examined and described.

Studies on derivatives of tetrahydro [1,3]-thiazine.
Archivum immunologiae et therapiae experimentalis, 1978In the course of studies on compounds with expected antiinflammatory and immunosuppressive activity a series of new derivatives of tetrahydro [1,3]-thiazine-4-one-6-carboxylic acid, tetrahydro [1,3]-thiazine-4,6-dione and 2-thiobarbituric acid have been synthetized.
