Efficient synthesis of 4,4-disubstituted-3,4-dihydro-1H-2,1,3-benzothiadiazine 2,2-dioxides

A simple method for the preparation of 4,4-disubstituted-3,4-dihydro-1H-2,1,3-benzothiadiazine 2,2-dioxides is described. Treatment of N-sulfonyl ketimines 2 and 3 with different carbon nucleophiles afforded the corresponding of 4,4-disubstituted-3,4-dihydro-1H-2,1,3-benzothiadiazine 2,2-dioxides 1...

Description
Summary:A simple method for the preparation of 4,4-disubstituted-3,4-dihydro-1H-2,1,3-benzothiadiazine 2,2-dioxides is described. Treatment of N-sulfonyl ketimines 2 and 3 with different carbon nucleophiles afforded the corresponding of 4,4-disubstituted-3,4-dihydro-1H-2,1,3-benzothiadiazine 2,2-dioxides 1 in isolated yields of 35–84%.
