Schroth, Werner published the artcileSynthesis and chemical behavior of 6-sec-amino-1,3-thiazine-2-thiones, Application In Synthesis of 6972-05-0, the publication is Monatshefte fuer Chemie (1988), 119(4), 463-76, database is CAplus.
The title compounds I (R = H, Me, OMe, Cl, Br; NR1R2 = pyrrolidino, piperidino, morpholino) have been prepared by ring transformation reactions of the isomeric 2-sec-amino-1,3-thiazine-6-thiones II (NR3R4 = NMe2, pyrrolidino, morpholino) via R2R1NCSCH:C(C6H4R-4)NHCSNR3R4 (III) and via cyclocondensation reactions of thiocarboxamides R2R1NCSCH:C(C6H4R-4)NH2, and R2R1N+:CClCH:C(C6H4R-4)OEt BF4– obtained from 4-RC6H4COCH:CCl2. The pathways differ specifically in scope and limitations. On the other hand III also react with alkylating agents to give 2,6-di-sec-amino-1,3-thiazinium salts, which are also available via alkylation of I and aminolysis.
