N-heterocyclic carbene-catalyzed atroposelective annulation for access to thiazine derivatives with C-N axial chirality
A catalytic atroposelective cycloaddition reaction between thioureas and ynals is developed. This reaction features the first NHC-catalyzed addition of thioureas to acetylenic acylazolium intermediates to eventually set up C-N axial chirality with excellent optical purities. The obtained axially chi...
