Uses
Sulfamide and its derivatives can also be used to prepare fused thiadiazine systems, Reaction with 2-aminoacetophenones affords IH-2,1,3-benzothia- diazine 2,2-dioxides 77 (65JOC3960). The corresponding 3,4-dihydro deriv- atives are readily available from 2-aminobenzylamines with either sulfuryl chloride (70M1443) or sulfamide (66USP3278532; 71MI055). These kinds of compounds can also be obtained from N-aryl-N'-alkylsulfamides and s-trioxane in a reaction involving cyclization by intramolecular sulfamido- methylation (79JOC2032) (Scheme 30).
