Abstract

Zusammenfassung Thiocarbamoyl compounds A (aliphatic and aromatic thioamides, thioureas, dithiocarbamates, thiosemicarbazones etc.) and β-chlorovinyl-ketones B react to 1, 3-thiazinium salts D (1–51) via S-ketovinyl-thioimidium derivatives C. The heterocycizations are easily performable starting directly from A and B in an one-pot procedure. An advantage of this straight-forward synthesis consists in the broad variety of ...
