Thiazine derivatives

Highly Regioselective Synthesis of Tetrahydro-2H-1,3-thiazin-2-ones via Rhodium-Catalyzed Carbonylation of N-Alkylisothiazolidines. — It is shown for the first
02- 162 time
that the title compounds are easily synthesized in good yield by reaction of
N-alkylisothiazolidines with carbon monoxide in the presence of a rhodium catalyst
and potassium iodide. The reaction proceeds site-selectively and provides a novel
approach for the synthesis of tetrahydro-2H-1,3-thiazin-2-one derivatives in one step.
