Schroth, W. published the artcileSynthesis of 1,3-thiazinium salts from β-chlorovinyl ketones and thio amide functionalized compounds, Category: amides-buliding-blocks, the publication is Tetrahedron (1982), 38(7), 937-48, database is CAplus.
Thiocarbamoyl compounds reacted with β-chlorovinyl ketones to give 1,3-thiazinium salts via S-ketovinylthioimidium derivatives E.g., condensation reaction of Me3CCSNH2 with 4-MeC6H4COCH:CHCl in HClO4 gave the intermediate 4-MeC6H4COCH:CHSC(:N+H2)CMe3 ClO4– which underwent acid-catalyzed cyclocondensation reaction to give 72% thiazinium salt I. The thiazinium salts react with nucleophilic reagents preferentially at position 6. E.g., substitution reaction of I with morpholine at -20° gave 94% thiazine II. The scope of the cyclocondensation reaction is discussed.
