title: Catalytic generation of cesium acetylide by CsF: synthesis of 1,3-benzothiazines from cyclic sulfenamides.
abstract: An efficient synthesis of enantiopure 1,3-benzothiazines has been achieved by reaction of cyclic sulfenamides and alkylpropiolate or tosylacetylene catalyzed by cesium fluoride.
