An improved synthesis of 2H-1,2,6-thiadiazine 1,1-dioxides by condensation of β-amino and β-chloro α,β-unsaturated ketones with sulfamides

Symmetrically substituted β-amino α,β-unsaturated ketones react with sulfamide giving 2H-1,2,6-thiadiazine 1,1-dioxides in excellent yields. Unsymmetrically substituted β-amino and β-chloro α,β-unsaturated ketones also react with benzylsulfamide to yield
