Catalytic Regio- and Stereoselective Alkene Sulfenoamination for 1,4-Benzothiazine Synthesis.

Chemistry, 2019
An alkene sulfenoamination reaction with 2-aminothiophenol is developed using iodide catalysis. This reaction renders access to useful 1,4-benzothiazines with good functional group compatibility including both electron-donating and electron-withdrawing ...

Trimeric aldolization product of 1,4-benzothiazine

Journal of the Chemical Society, Chemical Communications, 1977
2H-1,4-Benzothiazine, the parent system of the mammalian phaeomelanic pigments, is a highly unstable molecule which readily undergoes a reversible aldolization to form, mainly, the cyclic trimer (5).

Cycloaddition reactions of 1,3-benzothiazines - 6. Reactions of 1,3-benzothiazine derivatives with substituted acetyl chlorides

Tetrahedron, 1984
Abstract 6, 7-Dimethoxy-2 H -l,3-benzothiazine derivatives ( 1 , 8 ) react with substituted acetyl chlorides to give angularly condensed β -lactams ( 3a - d , 10 , 11 ). The cis compound 11 was epimerised to the trans derivative 12 .
